As Cheadle noted, it could have been worse, because if you listen closely, Ruffalo starts to say “Ha…” before then switching to “Everybody dies,” indicating he was about to “half” of all the heroes would die, a.k.a.
Technically Mark Ruffalo didn’t provide any specific details about Avengers: Infinity War when he and Don Cheadle were promoting the movie on Good Morning America, but he nonetheless let slip that a lot of heroes would die at the end.
Needless to say that Marvel is going to keep an even closer eye on Ruffalo in the future, and Cheadle even joked that the Hulk actor wouldn’t be allowed to do press for any movie for fear of accidentally spoiling something Marvel-related.
It’s been almost four full months since that interview, and as you can tell by Cheadle’s face during his recent appearance on Jimmy Kimmel Live!, he’s still astounded that Ruffalo delved into spoilery territory despite Cheadle warning him to tread cautiously.
