Fantastic Four' star Vanessa Kirby opened up about working with Robert Downey Jr. on the upcoming 'Avengers: Doomsday,' saying he does 'incredible work' in the film and 'is our leader' on set.

First Steps, I am convinced that Doctor Doom will be Avengers: Doomsday 's main character. The ending of The Fantastic Four: First Steps did not do much to actively set up Avengers: Doomsday, with the team remaining in their contained universe after defeating Galactus.

Robert Downey Jr will be introduced as Doctor Doom in Avengers: Doomsday – but what if he’s not the real Doom?
