Sure, when five cast members of the upcoming Avengers: Infinity War appear on Jimmy Kimmel Live!, you expect some hijinks. But we also learned what happens when you're an Avengers: Infinity War cast member who overshares.
As soon as he made what appeared to be a joke about sharing an Infinity War spoiler, Mark Ruffalo's cast members ratted him out as the least-trustworthy cast member, prompting Tom Hiddleston to share the time Ruffalo accidentally live-streamed a portion of Thor: Ragnarok on Instagram at the film's premiere.
In his own defense, Ruffalo, insisted the phone was in his pocket so viewers just heard the first 15-20 minutes of the film, but then relayed how a Disney rep came up to him in the middle of the screening, and poked him, telling him angrily, "Turn off your phone!" and just in general giving him the business for his clumsiness.
So, let this be a lesson to you: not even being one of the biggest, strongest superheroes around will save you from the wrath of studio PR people.
