James Jude Courtney started working at Universal Studios Hollywood as a tour guide before he was cast as Conan in the park’s Conan the Barbarian live show. Courtney applied his martial arts skills to the role, which demanded high falls and sword fights.
At Universal Studios, Courtney met actor Brian Thompson and stunt coordinator Alex Daniels, who helped him to branch out as a stunt performer. He also pursued acting studies at the Royal Academy of Dramatic Art and was coached by Stella Adler.
Courtney made his film acting debut in 1989 in The Freeway Maniac and continued acting through 2002. In 1997, he gained wider recognition in the role Der Kindestod in the Buffy the Vampire Slayer episode “Killed by Death”.
Courtney played Michael Myers in David Gordon Green’s horror film Halloween, the 2018 sequel to John Carpenter’s 1978 film of the same name. Green asked the film’s stunt coordinator Ron Hutchinson whether he knew an experienced stunt actor that was “6-feet-3, 200 pounds, and in his 60s,” upon which Hutchinson recommended Courtney. Green explained to Courtney his vision for Myers’s mannerisms, an amalgamation of the performance of Nick Castle, who originally played the character in 1978, and the addition of a feline style of movement, which Courtney tailored his portrayal to by observing the movement of his pet cat. He used Carpenter and Castle’s work on the original film to inform how the forty years that transpired between the events of the films would affect the character.
Courtney returned to the role for the film’s 2021 sequel, Halloween Kills, with Nick Castle once again sharing the acting credit, although Castle’s only scene in the film was excluded from the final cut. Courtney stated that his stunt work for the film, especially for scenes including fire, was among the most challenging of his career. He portrayed the character for a third and last time in 2022’s Halloween Ends, thus earning him the accolade of being the actor to portray Myers the most times. For Halloween Ends, director David Gordon Green made the decision to have Courtney physically portray the character for the entirety of the film for the first time, citing his “extraordinary work” in the previous films.
Honoring his portrayal of Michael Myers in 2018’s Halloween, October 19, the film’s United States opening day, was officially proclaimed James Jude Courtney Day in Warren County, Kentucky. Courtney was nominated for Best Actor at the 2019 Fangoria Chainsaw Awards alongside Castle for his work in Halloween. For his performance in Halloween Kills, Courtney was nominated for Best Villain at the 2022 MTV Movie & TV Awards.
