Marvel Studios president Kevin Feige has debunked a popular fan theory regarding Robert Downey Jr.'s Doctor Doom in Avengers: Doomsday.
Seven years after Endgame was released, the Oscar-winning actor is back in the MCU and, this time around, he will be playing the role of Victor Von Doom. Some fans have speculated that the villain might be introduced as a Tony Stark variant, or that his casting as Doom is a red herring for another actor.
However, it looks like the fan theories might not be true after all.
Kevin Feige Shuts Down Popular Doomsday Fan Theory About Doctor Doom
In an interview with Empire Magazine, Kevin Feige weighed in on the fan theories online that Robert Downey Jr.'s Doctor Doom in Avengers: Doomsday will be introduced as a Tony Stark variant.
He maintained that the Doctor Doom we will see in the upcoming film won't be a variant of Downey's previous character and that he would be introduced as another character that the actor plays in the MCU.
"Is Steve Rogers a Johnny Storm variant? People wondered, ‘Is Doom just a variant of another character? Is this just a shortcut to bringing back another character?’ The answer is no. He’s Victor Von Doom," the Marvel Studios president clarified.
This should shut down the ongoing fan theories regarding the portrayal of Doctor Doom in the upcoming film, since they are indicating that the character will be presented as its own and they have no intention of putting any twist, despite having Downey play him.
In a separate interview, Downey highlighted how he is enjoying playing the villain this time around, instead of being the hero.
"Remember Michael Douglas at the end of Falling Down? He goes, ‘I’m the bad guy?’ I had that realisation a couple of days into shooting because all the heroes are over there, and I’m the problem. And then I leaned in, and it was just this glorious time," he said.
"I like a bit of scorched earth. Whatever you think he may be entertaining, I would ten times it, and you’ll probably be closer to the ballpark."
