Music While living in St. Louis, Gunn founded a band, The Icons, in 1989, serving as lead vocalist. The group released the album
Mom, We Like It Here on Earth in 1994, and its songs "Sunday" and "Walking Naked" were featured in the film
Tromeo and Juliet. The Icons disbanded in the mid-1990s. Gunn has continued to work in music, composing songs for
Scooby-Doo,
Scooby-Doo 2: Monsters Unleashed, and
Movie 43.
Film and television Gunn began his career in filmmaking with
Troma Entertainment in 1996, for which he co-wrote the independent film
Tromeo and Juliet. Working alongside his mentor
Lloyd Kaufman, the co-founder of Troma, Gunn learned how to write screenplays, produce films, scout locations, direct actors, distribute films, and create his own poster art. That same year, he executive produced and starred in the mockumentary
LolliLove, directed by and starring his then-wife
Jenna Fischer. His film directorial debut was the 2006 horror-comedy
Slither, which was included on Rotten Tomatoes' list of the 50 Best Ever Reviewed Horror Movies. Gunn's next projects included the comedy short film "Humanzee!" which was originally intended exclusively for the Xbox Live's
Horror Meets Comedy series of short comedy films by horror directors, it was replaced with "Sparky and Mikaela" which debuted on Xbox Live on December 31, 2008. In an April 2009 interview on
The Jace Hall Show, Gunn described "Sparky and Mikaela" as being "about a human [and] racoon crime fighting team and they fight crime in both the forest world, among the furry animals, and in the human world". Gunn also has a short-form web series for
Spike.com titled ''
James Gunn's PG Porn''. In 2008, Gunn was a judge on the
VH1 reality television show
Scream Queens, where 10 unknown actresses compete for a role in the film
Saw VI. In 2009, Gunn announced he was going to write and direct
Pets, a comedy about a man who is abducted by aliens who want to turn him into a household pet, with
Ben Stiller,
Stuart Cornfeld and Jeremy Kramer producing. However, by March 2009, Gunn announced, "
Pets unfortunately, is done. I'm gone. I left the project for various reasons. I hope it sees the light of day somehow, but it won't be with me attached as director." In 2010, Gunn released
Super, a
dark comedy and
superhero satire starring
Rainn Wilson and
Elliot Page. He also directed a segment of the 2013 comedy anthology film
Movie 43 (2013); the segment starred
Elizabeth Banks and
Josh Duhamel. The film was critically panned. Gunn co-wrote and directed the
Marvel Studios adaptation of
Guardians of the Galaxy, which was released on August 1, 2014. His brother, Sean, has a role in the film. Gunn has appeared as an actor, mostly in smaller roles or uncredited appearances in his own projects. After
Dan Gilroy and
Jack Black separately lamented the proliferation of superhero films, Gunn responded in a Facebook post, saying in part: Gunn wrote and produced the
horror film The Belko Experiment, which was released in 2017. In 2016, he directed three
Stan Lee cameo scenes in one day, for the film
Doctor Strange and two unrevealed projects. Gunn wrote and directed
Guardians of the Galaxy Vol. 2 (2017). Gunn was slated to direct
Guardians of the Galaxy Vol. 3 in July 2018, but before the project started,
Disney severed ties with Gunn as the director amid controversy over
off-color jokes he had
tweeted. Gunn was rehired in March 2019 after a mass public appeal, many saying he was the reason of the previous movies' successes. In January 2019, he was officially confirmed to direct
The Suicide Squad. He also wrote, directed, and produced the
HBO Max spin-off show
Peacemaker centered on
The Suicide Squad character
Peacemaker played by
John Cena. Gunn also co-wrote and co-produced a live-action/animated film titled
Coyote vs. Acme, based on the
Looney Tunes character
Wile E. Coyote, for
Warner Animation Group.
Other media Gunn wrote a novel in 2000,
The Toy Collector, a story of a hospital orderly who steals drugs from the hospital which he sells to help keep his toy collection habit alive. In 1998, he and Troma's President Lloyd Kaufman co-wrote
All I Need to Know About Filmmaking I Learned from The Toxic Avenger, about his experiences with Kaufman while working at Troma. He wrote the story for
Grasshopper Manufacture's video game
Lollipop Chainsaw, working with game designer
Suda 51.
Firing from Disney and reinstatement In July 2018, amidst criticism of Gunn's past controversial jokes posted on social media between 2008 and 2012—topics included
child sexual abuse,
rape, and the
Holocaust—Disney severed its ties with him as the director of the upcoming
Guardians of the Galaxy Vol. 3 film. Gunn responded, describing the jokes as "stupid, not at all funny, wildly insensitive, and certainly not provocative like I had hoped". He continued apologetically, "Even these many years later, I take full responsibility for the way I conducted myself then. All I can do now, beyond offering my sincere and heartfelt regret, is to be the best human being I can be: accepting, understanding, committed to equality, and far more thoughtful about my public statements and my obligations to our public discourse."

San Diego Comic-Con, which took place in the days after Gunn's dismissal. However, when the first trailer for the film was released on December 8, Gunn's name was prominently featured, and the film opened in May 2019. In March 2019, Gunn was reinstated by Disney as director of the film after meeting with
Alan Horn, chairman of Walt Disney Studios. Gunn started production on
Guardians of the Galaxy Vol. 3 in October 2021, after
The Suicide Squad had been completed.
DC Studios '' in 2024 Gunn and frequent producing partner
Peter Safran had advised
David Zaslav, the CEO of the newly created
Warner Bros. Discovery, during his search for a new head of
DC Films. The duo impressed Zaslav, who decided to appoint them as the co-chairpersons and CEOs of DC Films, rebranded as "DC Studios". The two were given control over films, animation and television projects based on characters from
DC Comics. Gunn was to oversee the creative aspects and will be exclusive to Warner Bros. Discovery during his tenure, except for his prior commitments to Disney. The two first worked together on the 2000 superhero comedy film
The Specials written by Gunn with Safran as co-executive producer, with subsequent collaborations including Gunn's 2008 short films
Sparky & Mikaela and
Humanzee!, the television series ''
James Gunn's PG Porn (2008–2009), The Belko Experiment (2016) and the DCEU film The Suicide Squad'' (2021). The two assumed their positions on November 1, 2022. In December 2022, Gunn announced that he was writing a film about a young
Superman during his early years in
Metropolis, later revealed to be titled
Superman and released in July 2025; in March 2023 it was confirmed Gunn would also direct the project. In January 2023, Gunn and Safran revealed their plans for future DCU films, with the first chapter being titled "Gods and Monsters". Gunn also wrote a seven-episode animated series titled
Creature Commandos, based on the
comic book team of the same name, and released ahead of
Superman in December 2024, and also worked on the HBO Max series
Waller, a spin-off of
Peacemaker focusing on the character of
Amanda Waller, with Christal Henry writing and
Viola Davis reprising her role from previous DCEU projects. Gunn is also involved in multiple other DC projects, including producing
Supergirl due for release in 2026. Following the success of
Superman, Gunn announced a follow-up film in September 2025, titled
Man of Tomorrow, using new artwork from
Jim Lee. The film is set to be released in 2027, with
David Corenswet and
Nicholas Hoult expected to reprise their roles. The
second season of
Peacemaker was also produced by the Gunn and Safran-led DC Studios. Most of the
first season is
canon to the DCU, but only the second season, written in 2023 and aired in August–October 2025, is part of the Gods and Monsters chapter. == Political views ==
