Long time no post haha. I'm sure you already know, but Mark Ruffalo was doing an AMA on Reddit today.

Heres my fave so far:
Is your friendship with Robert Downey Jr. in real life as good as it is on the screen between your characters?
Better. We have a really good friendship. We've known each other since before Zodiac. And he's kind of like an older brother that I wish I had. He sort of looks out for me, and I remember when the role came up in the movie, I reached out to him, I was nervous about it, I said "I don't know if I can do this" and he said "It's alright buddy, I gotcha."
