It has almost become a tradition for the next MCU movie's big twists to be figured out by fans long before the film's actual release, forcing the directors and actors to play coy for months. The most recent example of this revolved around Sadie Sink's role as Jean Grey in Spider-Man: Brand New Day, which wasn't confirmed before the movie's release despite it being the worst-kept secret in the world. Now the Russo Brothers are going through the cycle again ahead of Avengers: Doomsday after being pressed with questions about Mark Ruffalo's Hulk.
