Majors debuted his role as Kang, who was supposed to be the next major threat in the Marvel Cinematic Universe, in 2023’s Ant-Man and the Wasp: Quantumania having previously had a small role as an adjacent character in the Disney+ series Loki.
In preparation for the role of Maddox, Majors reportedly ate 6,100 calories a day for four months and trained for six hours a day to obtain and maintain the extreme muscular physique required.
Michael B Jordan has said that he is “proud” of Jonathan Majors and that he would work with the actor again despite being charged with assaulting his former girlfriend.
This caused Marvel to rename 2026’s Avengers: The Kang Dynasty to Avengers: Doomsday, with Robert Downey Jr making a divisive return to the MCU as Doctor Doom.
Directed by Elijah Bynum, the film stars Majors as Killian Maddox, an aspiring bodybuilder who abuses steroids in his quest for recognition.
