Despite 27 actors being confirmed for Avengers: Doomsday during Marvel's surprise cast announcement, Robert Downey Jr – who's set to play Doctor Doom in the upcoming superhero flick – was the only one to show up in person.
After a five-and-a-half-hour livestream that revealed Chris Hemsworth, Ian McKellen, Channing Tatum, and more would be in the movie via set chairs, the Iron Man star strolled into frame and sat on his own. He then looked over his right shoulder, put a finger to his lips, and shushed everyone tuning in.
