Marvel Studios has released the first high-definition looks at Avengers: Doomsday, which appears to feature a large ensemble cast, including the X-Men and Fantastic Four. The release includes concept art and a first look at Doctor Doom, with some outlets suggesting that Robert Downey Jr. will play the character, although this is not universally confirmed. The art also provides a glimpse of Doctor Doom's mask and throne, ahead of the film's release.
