Captain America: Civil War has started filming and we already know that almost all the Avengers are going to be in it but there has been no official word that the Hulk will appear in the film. Well that may be changing per some recent tweets from Mark. “The Marvel family gets just a little bit bigger,” he tweeted. He also posted a photo on Tumblr announcing the release date of the film. “Welcome to the wild party! Looking forward to this amazing cast.” Nothing official of course but it sounds like he will be making an appearance to me.
