Avengers: Doomsday Goes Before the Camera With a 'Living' Script, Russo Brothers Say

Marvel’s Avengers: Doomsday will begin production without a finished script, with Joe and Anthony Russo describing the screenplay as a 'living organism' that grows through improvisation and actors’ contributions. Robert Downey Jr. returns to the MCU as Doctor Doom after Jonathan Majors was dropped amid legal troubles, and Marvel overhauled the project accordingly, a shift contrasted by James Gunn’s insistence that DC productions require finalized screenplays.
