Mark Ruffalo is back at leaking Avengers 4 titles on Jimmy Fallon’s show!

Mark is all set to appear on Fallon’s show on Saturday to talk about the upcoming elections in America and to get people to register to vote.

The host also got him talking about his upcoming, highly anticipated movie, Avengers 4. However, he doesn’t stop at the title and begins reciting an entire Hulk scene from the movie, jumping on the couch and vandalizing Jimmy’s set—but his words bleeped out through the entire maniacal episode.

Mark Ruffalo has done it again. Keeping true to his uncontrollable persona in the Avengers movies the actor may have once again revealed a big spoiler on The Tonight Show with Jimmy Fallon and this time, director duo Anthony and Joe Russo are making sure he pays for it.

Mark, you’re fired.

.@JimmyFallon, I trust that you will cut my spoiler slip on the show tonight. That was “off the record” homey. Please don’t get me in trouble with Marvel (Barry) again. DM me back. M
