It’s been one year since Marvel Studios announced that Robert Downey Jr. is returning to the MCU as Doctor Doom in Avengers: Doomsday and Avengers: Secret Wars. Recently, Doomsday wrapped filming.
In a recent interview with ComicBook.com, Iron Man 3 director Shane Black said Downey Jr.’s portrayal of Doctor Doom is “going to singlehandedly reinvigorate the entire comic book movie industry.”

At first, Black thought the casting seemed like a cynical idea, revisiting the actor who always saves the genre. However, after seeing Downey’s approach, Black is convinced: “It’s going to work. It’s really going to work.” He hinted that Downey has brought something fresh to the role but said he’s “not at liberty to say anything” more.
Black said, “I think he’s going to singlehandedly reinvigorate the entire comic book movie industry with that.”
He added, “I mean, it seemed at first like a cynical idea — you know, ‘Oh, let’s just go back to the well of the one guy that always seems to save us.’ But it’s going to work. It’s really going to work. And he’s brought something to it… I’m not at liberty to say anything, not that I know. I’m thrilled because I’ll be first in line to see that. I haven’t seen all the Marvel movies, but I’ll see that one first.”
Here’s the plot synopsis for Avengers: Doomsday:
