IGN has published an interview with Mark and Robert made at the set of Avengers: Age of Ultron in London, earlier this year. There’s a few teasing, minor spoilers, so be warned about it!
Q: I’m curious about this cool little house party that goes on in this movie. Are you there as the Hulk or as Banner?
Ruffalo: Banner. Indoors I have to be Banner. That’s kind of the rule. It’s like leave your shoes at the door. It’s like leave your Hulk at the door. Yeah, they don’t like him. Hulk still has a little bit of a ADHD kid thing going on. [Laughs]
Q: How much dialogue might Hulk have in the film? Cause in the first movie he has two amazing lines. ‘I’m always angry’ and ‘Puny God.’ Does he have anything like that in the sequel? Any one-liners?
Ruffalo: We’re sort of still working that out. He will. We’re just kind of trying to it figure out. There’s a couple of different places to do it, but he’s not going have a soliloquy. Not yet anyway. Joss has a couple of ideas of where to put things in.
