Films Original continuity (1978–1995) Dr. Samuel Loomis first appears in the original
Halloween (1978). Assigned as the psychiatrist to six-year-old Michael Myers after the boy
killed his own sister, Loomis spent eight years trying to reach Myers before coming to the conclusion that he was "purely and simply evil" and advocating that Myers never be released. Fifteen years after Myers' first murder, Loomis and colleague Marion Chambers prepare to escort Michael from Smith's Grove Sanitarium to court; Loomis plans to give Michael
Thorazine to ensure he will have no chance to be released back to society. However, upon arrival they find that the sanitarium's patients are wandering loose, and in the confusion an escaped Michael steals their car. Loomis suspects Michael plans to return to his hometown of Haddonfield, Illinois; investigating the Haddonfield cemetery he discovers that Judith Myers' tombstone is missing. He meets with Sheriff Leigh Brackett, and the two begin their search at Michael's former home. While a skeptical Sheriff Brackett patrols the streets, the doctor stays at the house believing that Michael may desire to return "home". Loomis hears two children frantically fleeing a nearby house; investigating, he finds Michael attacking
Laurie Strode. Loomis draws his
revolver and shoots Michael six times, knocking him off the balcony, but when he goes to check Michael's body he finds it missing. An unsurprised Loomis stares off into the night, while Laurie begins sobbing in terror.
Halloween II (1981) begins at the final moments of the first film. Laurie is taken to Haddonfield Memorial Hospital, while Brackett accompanies Loomis in his search for Michael. The pair spots a masked figure that may be Myers, but he is struck by a car and immolated which confounds identification of the body. Sheriff Brackett learns his daughter
Annie was killed by Michael, and angrily blames Loomis for letting him escape and leaves the search to Deputy Gary Hunt. Investigation of the burned corpse reveals it was not Myers, whose trail is picked up at the local elementary school. As Loomis investigates he discovers clues connecting Michael to the occult practice of
Samhain, suggesting an explanation to his seeming invulnerability and murderous desire. The search is interrupted by a returning Chambers: the governor has ordered Loomis to return immediately to Smith's Grove accompanied by a
US Marshal. Along the way, Marion shares that a previously sealed file reveals that Laurie is Michael's sister, adopted by the Strodes after the death of her parents. Realizing that Michael is after Laurie, Loomis forces the Marshal to drive to Haddonfield Memorial at gunpoint. The trio reach the hospital to defend Laurie. As Marion attempts to contact the police, Michael kills the Marshal and chases Loomis and Laurie into an
operating theater. Michael stabs Loomis in the stomach, seriously wounding him, but Laurie blinds Michael by shooting him in the eyes. The pair fill the room with
oxygen and
ether. Laurie flees while Loomis ignites the flammable gases, blowing up the operating room. In the original timeline, Loomis dies in the explosion, while he miraculously survives in the Thorn Timeline (the fourth through sixth films) as he is thrown out of the room by the explosion and is knocked unconscious. Michael, engulfed in flames, staggers out of the room before finally collapsing lifeless in the original timeline, while surviving, albeit in a coma, in the Thorn Timeline.
Halloween 4: The Return of Michael Myers (1988), which begins the Thorn Trilogy, picks the story up ten years after the events of
Halloween II. Michael has been comatose since the explosion, but awakens when he learns Laurie Strode has died in a car accident, leaving behind a daughter,
Jamie Lloyd. Loomis heads to Haddonfield after learning that Michael has escaped. He follows Michael to a gas station, but Myers escapes in a tow truck and causes an explosion, destroying Loomis's car in the process. Catching a ride to Haddonfield, Loomis warns the new sheriff, Ben Meeker, that Michael has returned. Michael attacks the police station and kills all of the officers. A lynch mob is formed by the town's men to kill Michael once Loomis reveals he's returned, refusing to let Michael cause a massacre and the latter goes to protect Jamie Lloyd from her uncle. After Michael Myers is shot and falls down a mine shaft, Jamie and Rachel are brought back to their foster parents' house, where Loomis arrives with Sheriff Meeker, the former being convinced that Myers has died. Without warning, Jamie stabs her foster mother giving her an appearance similar to six-year-old Michael's first kill. Sheriff Meeker prevents a horrified Loomis from shooting her as the group realizes that Jamie is following in Michael's footsteps.
Halloween 5: The Revenge of Michael Myers (1989) takes place a year later as Loomis is assigned to Jamie at the Haddonfield Children's Clinic. Aware that Michael is still alive, and discovering that Jamie is telepathically linked with him, Loomis constantly pressures her to inform him of Michael's whereabouts, but Jamie is too
traumatized to tell him. When Michael returns, Loomis sets a trap for Myers at his house, which involves Jamie performing an eerie recreation of Judith Myers' final moments before her murder. Michael arrives, and Loomis tries to reason with him, proposing that he fight his rage and redeem himself through a positive relationship with Jamie. Loomis's words seem to work at first, as Michael calmly listens to him and lowers his knife, but when Loomis reaches to take away Michael's knife, he subdues him. When Loomis awakens, he uses Jamie as bait, and lures Michael into a trap to weaken him with a
tranquilizer gun. After beating Michael unconscious with a wooden plank, Loomis suffers a stroke and collapses. In
Halloween: The Curse of Michael Myers (1995), Loomis has retired and lives as a hermit in a small home on the outskirts of Haddonfield. He is visited by his old colleague Dr. Terence Wynn, chief administrator at Smith's Grove Sanitarium who tries to persuade Loomis to return to Smith's Grove, but the latter declines. At the same time they hear the voice of Jamie Lloyd on the radio begging Loomis to help her. The following morning Jamie's body is discovered, and Loomis is devastated. He is later approached by Tommy Doyle at the hospital who tells him about his discovery of Jamie's child, Steven. It is revealed that Michael is under control of the curse of "
Thorn", a power he has been cursed with by a druid cult led by Dr. Wynn since he was a young boy after hearing voices telling him to kill his family. After this discovery, Loomis and Tommy are drugged and later follow Wynn to Smith's Grove who abducted Danny, his mother, and Steven with the help of his cult followers. Wynn reveals that Jamie's baby represents a new cycle of Michael's evil that he kept secret from most of the cult who were focused on inflicting the curse onto a new child, Danny. Loomis is knocked unconscious after criticizing Wynn. Later, Michael butchers Wynn's team of staff surgeons and Wynn himself during a medical procedure with Danny and Steven sitting in a room next door. Tommy then joins forces with Kara Strode (Danny's mother and Laurie Strode's cousin) in order to protect Jamie's baby from Michael. They succeed, and after regaining consciousness, Loomis helps them escape the hospital while Tommy subdues Michael by injecting him with large quantities of tranquilizers. As Tommy, Kara, Danny, and Steven leave, Loomis refuses to come with them as he has "a little business to attend to". Back inside the building, as seen in the theatrical version, Michael's mask is shown lying on the floor of the lab room, and Loomis is heard screaming in the background, leaving the fate of both men unknown. In the original "Producer's Cut" of the film, after telling the others he has got "a little business to attend to", Loomis walks back into the sanitarium to find a seemingly defeated Michael lying on the floor of the main hallway, after being stopped by Tommy, who used
runes. Upon removing the mask, Loomis finds Dr. Wynn, who was forced by Michael to switch outfits so he could escape. With his dying breath, Wynn grabs Loomis's hand and says, "It's your game now, Dr. Loomis." After Wynn dies, the Thorn symbol appears on Loomis's wrist; realizing now that the Thorn Curse has passed on to him, and that he himself is now to act as the leader of the cult, Loomis screams in terror and disgust.
H20 continuity (1978–1981, 1998–2002) Ignoring the events of the previous three films,
Halloween H20: 20 Years Later (1998) establishes that Michael Myers survived the explosion in 1978 and has been missing for twenty years since then. He arrives and kills Marion Chambers at Loomis's retirement house. Two investigators discuss what they know about Loomis's life in this alternate version of the series, following the events of the first two films. Having also survived the explosion in 1978, Loomis was under Marion's care at this house in his final years before dying. However, even after nearly 20 years, Loomis refused to believe that Michael was dead, and devoted the rest of his life to studying all information about his former patient. The two investigators enter his private study, and find that the walls are covered with photographs, sketches, and newspaper articles about Michael. During the opening credits, Loomis' speech to Brackett about his first meeting with Michael is heard in a voiceover (provided by
Tom Kane).
Remake continuity (2007–2009) A new version of Dr. Samuel Loomis appears in the
remake (2007). In the film, Dr. Loomis seems not to have contempt for Michael, and Michael doesn't truly see him as his nemesis. Their relationship with one another is more of a tragic friendship. Loomis does not immediately shoot Michael, but tries to reason with him. Loomis is first seen as a
child psychiatrist brought in by ten-year-old Michael Myers' school to speak with Michael's mother, Deborah. After seeing the various animals Michael has tortured and killed, he recommends that the boy get help. After Michael commits four murders on Halloween, he is put under Loomis's care at Smith's Grove Sanitarium. On some days the two talk peacefully, on others Michael has outbursts of violent rage. Fifteen years later, Loomis writes a best-selling book based on Michael's treatment called "The Devil's Eyes". On his last day at Smith's Grove, Loomis tells Michael that he has tried but cannot help him anymore. He also tells Michael that he has become something like his best friend. After Michael escapes, Loomis concludes that his former patient is going to Haddonfield. Once there, he enlists the help of Sheriff Lee Brackett, and also buys a gun. Loomis comes to believe that Michael has returned to find his little sister, Laurie, who Brackett helped get adopted by the Strodes after her mother committed suicide. Michael succeeds in tracking Laurie down, killing her friends and two police officers in the process. Loomis is alerted of Michael capturing Laurie by Tommy Doyle and Lyndsey Wallace, the children Laurie is babysitting, and sets off to the Myers house. There he confronts Michael as he approaches Laurie, begging Michael to stop, but as Michael ignores him and continues forward, Loomis is left with no choice but to shoot Michael. Loomis rescues Laurie, but Michael soon reawakens to continue the attack on his sister. Loomis again tries to reason with him at which point Michael lets Laurie go and subdues Loomis. In the unrated version of the film, when Michael is in pursuit of Laurie through the house, Loomis grabs his foot to try and stop him. Michael shakes him off and Loomis blacks out. In the film's original ending, Loomis is successful in convincing Michael to let go of Laurie as he is surrounded by police officers, telling Michael he "did the right thing". Despite Loomis's protests, however, Michael is killed shortly afterwards in a hail of gunfire, and the film ends with Loomis looking down sadly at his former patient's corpse. In the
sequel (2009), Loomis's character is revised; he is now seen as a greedy, arrogant mercenary who is profiting from the murders of the previous film. He does not believe Michael is alive and becomes annoyed and angry when asked about it. He goes on a tour to promote a new book, "The Devil Walks Among Us", while his assistant is shown to be disgusted with his campaign. In the climax of the film Loomis, after realizing Michael is still alive, realizes that he has changed for the worse and tries to save Laurie, this time unarmed. Michael ambushes Loomis and kills him by slashing his face and stabbing him in the chest. In the unrated version, Michael tackles Loomis out of the shack and then stabs him in the stomach while Loomis is still trying to reason with him. With Loomis injured and unconscious (it is not revealed whether he lived or died), the police open fire on Michael, killing him. Laurie, now completely insane, leaves the shack, picks up Michael's knife and walks over to Loomis's unconscious body. Against Brackett's orders, the police open fire on Laurie, apparently killing her too.
Blumhouse continuity (1978, 2018–2022) Halloween (2018) is a direct sequel to the first film, ignoring all other series entries. Taking place forty years later, it is established that Michael was arrested following his 1978 killing spree and has spent the last forty years imprisoned in Smith's Grove Sanitarium. Loomis does not appear in-person, having died an unspecified time ago prior to the film's events.
True crime podcasters uncover a 1979 audio recording of Loomis (voiced by Colin Mahan) giving a statement on his "former patient", advocating for Myers' execution and immediate
cremation and voicing a desire to witness as Myers is put to death and destroyed. Michael's new psychiatrist, Dr. Ranbir Sartain (
Haluk Bilginer), is established as a former student of Loomis's and even referred to as "the new Loomis" by Laurie Strode; however, he has a different perspective on Michael than Loomis's belief that he is "pure evil". In the sequel,
Halloween Kills (2021) Loomis (portrayed by Tom Jones Jr., and voiced by Mahan) is depicted in flashbacks portraying Myers' detainment by police forty years prior in the aftermath of his 1978 killing spree (events briefly mentioned in the prior film). Haddonfield officer Hawkins encountered Michael at the Myers residence, shortly before the arrival of Loomis accompanied by the rest of the police department. The doctor questions Hawkins if Michael killed the officer's partner, but gets no response. Loomis attempts to execute the detained Michael, but is stopped by a remorseful Hawkins who did not believe Michael deserved death for his crimes. Decades later, an older Hawkins blames himself for the deaths following Michael's 2018 escape and feels tremendous guilt for stopping Loomis that night. }
Literature Samuel Loomis's first literary appearance was in October 1979, in Curtis Richards' novelization of
Halloween, which largely follows the events of the film. He also appeared in the 1981 adaptation of
Halloween II written by Jack Martin; it was published alongside the first film sequel, with the novel following the film events, with an additional victim, a reporter, added to the novel. The final novelization to feature Loomis was
Halloween IV, released October 1988. The novel was written by Nicholas Grabowsky, and like the previous adaptations, follows the events of
Halloween 4: The Return of Michael Myers. Loomis appears in the online short story
Halloween: Sam, focusing on what happened to his character in the
H20 timeline after
Halloween II. Written by Hutchinson and featuring illustrations from
Autopsis Marcus Smith,
Sam is a prose short story available exclusively for download at the website HalloweenComics.com. It explores the life of Dr. Loomis, including his backstory and relationship with Elizabeth Worthington, a journalist he met during
World War II. In 1995, Michael Myers visits the ailing Dr. Loomis in a hospital and murders Elizabeth in front of him. Loomis attempts to stop him, but dies of a coronary failure. In the comic
Halloween: One Good Scare, Loomis is revealed to have a son, David Loomis, who like him, is a doctor at Smith's Grove Sanitarium. Although continuing his father's work, David is careful not to inherit his obsession with Michael Myers. However, when Lindsey Wallace is admitted to Smith's Grove claiming that Michael is stalking her, he finds history repeating itself. David neglects his other patients to interview Lindsey, investigates Michael's history, and even visits his childhood home in Haddonfield. However, on Halloween night in 2003, Michael arrives at Smith's Grove, murdering his way through the staff to get to Lindsey. David tries to protect her, but his fear gets the better of him and he hides as Michael drags Lindsey away to her death. Michael leaves behind a cracked picture frame containing a photograph of David and his father, a message that he plans to return for him. == Characterization ==
