If I had to guess I’d say Norton is still pissed he didn’t make it into The Avengers and Renner did.
Here’s my idea of the dialogue for the scene:
Norton: Dude, I practically wrote The Incredible Hulk!
Renner: So? I was in Thor!
Norton: Yeah, for like, 1/2 a second. I missed your scene because I sneezed and blinked.
Renner: Rufallo is the man!
Norton: Eff, you! It’s on!
What do you think?
The Bourne Legacy hits theatres August 3rd.
