Infinity War directors Anthony and Joe Russo say they keep secrets from their cast to prevent the stars from feeling pressured over spoilers.
Famously loose-lipped Hulk star Mark Ruffalo once let slip ?everybody dies? during a July 2017 appearance on Good Morning America.
ComicBook.com reports that Ruffalo dropped the spoiler nine-months before Infinity War was released.
Asked about their reaction to Ruffalo?s faux pas, Joe Russo joked, ?We fired him.?
In October, Ruffalo appeared on The Tonight Show and dished a flurry of censored Avengers 4 ?spoilers.?
He was subsequently ?fired? by the Russos over Twitter.
Joe Russo later confirming Ruffalo was still terminated as part of the running gag.
