Seems like The Hulk is suiting up to join Civil War!

Mark Ruffalo has been dropping lots of hints on social media that Bruce Banner will be among the many recruited to fight in the next Captain America movie.

Captain America: Civil War adds even more actors to its cast

When the most recent cast list was announced last week, The Hulk was notably absent. At the end of Avengers: Age of Ultron (SPOILER ALERT!), his character disappeared, but Marvel usually likes to tie up that sort of loose end.

On Thursday, Ruffalo tweeted a photo of the movie logo and wrote, "The Marvel family gets just a little bit bigger."

And on his official Tumblr page, he posted the movie logo again, and wrote:"Marvel Studios Begins Production on Marvel's 'Captain America: Civil War'. Welcome to the wild party! Looking forward to this amazing cast."

So... that seems pretty clear. There's been no official announcement from Marvel, but seeing as Ruffalo hasn't been abducted to a secret S.H.I.E.L.D. black site for gabbing, we imagine they must be drafting one now!

Captain America: Civil War will hit theaters May 6, 2016.
