Bruce Banner/Hulk actor Mark Ruffalo has a reputation for inadvertently spoiling Marvel Studios films he's been involved in - and this time, he may have spilled the beans on the still unannounced title of Avengers 4.
First, Ruffalo appeared on The Tonight Show, where he appeared to tell host Jimmy Fallon the film's still secret title - but his speech was censored in what appeared to be a rehearsed bit.

Then, over on Twitter, a fan called for Ruffalo to reveal the film's title - for real - to which Ruffalo responded by getting (gently) political, quipping "It's Avengers 4: Register to Vote."
The still officially untitled Avengers 4 is due out in theaters May 3, 2019.
And if you're not already, you really should register to vote.
