Adam Baldwin was cast in the role of John Casey, announced on February 8, 2007. Schwartz had Baldwin in mind for the role almost from the beginning of the casting process. Although the character of Casey has received relatively little attention, Schwartz indicated in interviews that "
Chuck Versus the Undercover Lover" established a lot of what made Casey, Casey. He received further development in "Chuck Versus the Sensei," when it's revealed that his former mentor had turned rogue. Most lately, Casey's beginnings, along with the revelation that John Casey was not his birth name, was hinted at during "
Chuck Versus the Fake Name" before being revealed in "
Chuck Versus the Tic Tac", along with significant present-storyline development, including his dismissal from government employment. Much of Casey's personality and background is revealed through small details that surface in episodes, often used to humorous effect. Interviews with
Josh Schwartz and Chris Fedak at
San Diego Comic-Con 2009 have indicated Casey's role will develop from strictly a protector to take on aspects of a mentor/student relationship with Chuck. Chris Fedak has also confirmed that Casey's family will be revisited later in Season 3.
Branch of Service Confusion throughout the series over Casey's branch of service was resolved in "
Chuck Versus the Angel de la Muerte," when he both identifies himself as a
Marine and the letters USMC are clearly visible stamped on his dog tags. "
Chuck Versus the Tic Tac" had previously supported the theory that Casey was a Marine officer, and his recruitment into the special forces is depicted in a flashback. Furthermore, he constantly wears a class ring resembling the
United States Naval Academy, a commissioning source for Naval and Marine officers. He wears his Marine Corps
Blue Dress "B" uniform when staging his own funeral in "Chuck Versus the Couch Lock".
Rank In addition to confusion over his branch of service, the series was also ambiguous over the rank Casey was promoted to in "
Chuck Versus the Colonel." Throughout the episode, he is referred to as "Colonel Casey." Although normal rank progression from major is to be promoted to lieutenant colonel, the episode never establishes whether he was promoted to this rank or full colonel, as both ranks are frequently referred to as "colonel" in casual usage, and "colonel" is the proper honorific used when addressing officers of either rank. "
Chuck Versus the Couch Lock" ultimately clarified Casey's rank when he is seen wearing the eagle insignia of a full
colonel with his dress uniform, confirming that by this episode Casey had received a promotion to "full bird colonel." However it is still unknown whether he skipped ranks directly to full colonel, or if he was initially promoted to
lieutenant colonel during the events of "Chuck Versus the Colonel" and had since been promoted again.
Awards and decorations Awards and decorations identified from a close-up of Casey's/Coburn's "fruit salad".
Continuity "Chuck Versus the Tic Tac" introduced further confusion into Casey's age, service, and background. Although in "Chuck Versus the Angel de la Muerte" he mentions having attempted to assassinate Premiere Goya at Beckman's personal orders on several occasions in the early 1980s (once as early as 1982) and further admitted pride in the number of Goya's men he killed fighting against the Communist revolution in Costa Gravas, the name "John Casey" did not even appear in the government's records until 1989. Beckman herself gave no indication of having known Casey was born as Alexander Coburn until his file was opened after his apparent treason. In "Chuck Versus Santa Claus" Casey is seen calling his "mother" and identifying himself as "Johnny Boy." The character's age is implied to be considerably older than that of Baldwin in "Chuck Versus the Couch Lock". His ribbons include the
Vietnam Service Medal with three
campaign stars, the
Vietnam Gallantry Cross (unit award),
Vietnam Civil Actions Medal (unit award), and
Vietnam Campaign Medal. Even if his three campaign stars are for the final three campaigns in Vietnam for which campaign stars were awarded, he would have had to have been fighting in-country on or before 29 March 1972, the last eligible day of "Consolidation II" (see
Vietnam service campaign dates), thereby placing Casey well into his fifties. Still more out of place is his
Philippine Independence Medal which has not been awarded since 1948.
See #Awards and decorations. The series never addresses these continuity conflicts.
Personality John Casey was described by Sarah in "
Chuck Versus the Intersect" as a "burnout", although the exact meaning of this was never explained. Although he disagreed with Sarah's feelings for Chuck in "Chuck Versus the Crown Vic", he later attempted to defend her in front of Beckman when Sarah was to be replaced by CIA agent Alexandra Forrest, insisting that Beckman allow Chuck to state his own case as to why he worked well with Sarah and admits that she is the best partner he's ever had. Chuck has even stated that even the reason Casey acts tough is because deep down, he really does care for Chuck and Sarah not only as his partners, but as his friends and that he's just scared to show his true emotions. The depth of his personal feelings for Sarah and Chuck are illustrated in "Chuck Versus the Final Exam" and "Chuck Versus the American Hero," when he helps Chuck "cheat" on his Red Test by killing the mark. He later confessed to Sarah that he pulled the trigger because Chuck could not, as he believed the knowledge would convince Sarah she really did still love him (although Sarah had already decided to leave with Chuck). Twice in "Chuck Versus the Honeymooners" Casey offered Chuck and Sarah the chance to escape to live out their lives together, reminding Sarah of his own choice when he faked his death to be sure it was what she genuinely wanted. Despite his support for the couple's relationship, Casey is nonetheless disgusted by their public displays of affection. In "
Chuck Versus the Tooth" the sincerity of Casey's regard for Chuck is revealed when he independently visited Dr. Leo Dreyfus to offer his help in determining what was happening with Chuck when the Intersect apparently began to malfunction. Casey has a deep sense of personal honor that occasionally comes into conflict with his sense of duty to his country; in particular, he personally objects when a person has served his country honorably and is nevertheless slated to suffer as a result of government actions. When it appeared that the replacement Intersect was ready, despite the antagonism he often expressed toward Chuck, he did not want to terminate him and felt that Chuck's service to the government entitled him to a better fate than termination. However he is also loyal to his government, and when it was sufficiently explained to him that leaving Chuck alive would place the country in danger, he was prepared to carry out his instructions regardless of his personal feelings. Casey is also a skilled martial artist, which is demonstrated when he fights his old
sensei in "
Chuck Versus the Sensei", although Casey was forced to retreat when he fought Sarah in "Chuck Versus the Helicopter". He has demonstrated a remarkable tolerance to pain and extreme endurance. He broke his own thumb to escape a set of handcuffs in "Chuck Versus the Suburbs," was able to remain awake and function relatively normally after being shot with a tranquilizer dart in "Chuck Versus the Helicopter," and it took Chuck three tranquilizer darts to put Casey down in "
Chuck Versus the Dream Job." In "
Chuck Versus the Fake Name" Casey not only encouraged Chuck to torture him to secure his cover with a pair of mobsters contracting for The Ring, but took Chuck completely removing one of his teeth without
anesthesia in stride and casually shrugged it off as no longer needing a trip to the dentist for treating a cavity. Casey is also exceptionally strong. When Carina cuffed him to a bed in "
Chuck Versus the Wookiee" he managed to free himself by tearing apart the frame with minimal leverage and no assistance, and ripped an entire radiator from the wall of a motel room in "Chuck Versus the Colonel," and, on several occasions, has lifted and throttled fully grown men off the floor literally single-handedly: Chuck Bartowski in "
Chuck Versus the Undercover Lover"; Col. James Keller (whose neck he then snapped) in "
Chuck Versus the Tic Tac"; and Morgan Grimes in "
Chuck Versus the Couch Lock". He can turn almost anything into a weapon, including the aforementioned bed frame and radiator, as well as household appliances. Casey carries a custom
SIG Sauer P229 with a two-tone accented design, often being confused with the Equinox model (Equinox model being equipped with accessory rails, whereas Casey's is not). Casey's sidearm is also modified with
Crimson Trace laser grips and mounts for a suppressor throughout the series. A significant amount of humor in the series centers around Casey's demeanor and random moments that are completely incongruous with his tough image, such as unexpectedly singing a note to which a puzzle is keyed and revealing having been a choir boy with perfect pitch, and dancing to 1990s music (specifically
Hanson's "
MMMBop") while undercover as a DJ at Sarah's high school reunion. While working at the Buy More in the days leading up to Christmas 2008, Casey had been assigned to man the gift-wrap counter and was so distraught over the resulting paper cuts that he had band-aids on all his fingers. He is also somewhat vain as shown in "Chuck Versus the Three Words". When instructed to pose as Carina's father, he insists that he be a young uncle. He frequently responds to situations with monosyllabic grunts, which Chuck can recognize and has even numbered, and often tosses off one-liners reminiscent of cliché action films, Casey goes rogue again, along with Morgan, Chuck, and Mary Bartowski, to save Sarah's life. With Operation Bartowski cancelled and the team all dismissed from government service, Casey and Morgan are hired by Chuck and Sarah for their private spy operation. He told Jane Bentley in "
Chuck Versus the Masquerade" that he had no intention of leaving Burbank, indicating that Castle would be the terminal assignment of his military career. It is unclear whether Casey was dismissed again or if he retired from the Marine Corps. ==Relationships==
