Mark Ruffalo – Infinity War

The Hulk star was trying to swerve Thor: Ragnarok spoilers at the D23 Expo in 2017 but then ended up giving away a major Infinity War spoiler instead. “Wait until you see this next one, everybody dies,” Ruffalo laughs before realising what a monumental mistake he had made.
Don Cheadle was unimpressed though and funnily enough, it barely got spoken about at the time. The clip went viral after the release of Infinity War so the actor kind of got away with it.
