But are they actually friends? It doesn't seem like that to me... I've seen RDJ in other interviews with people he really does have a good relationship with, and these are different. I feel like they are trying but don't really get each other. Or is that just because the movie? Also, Robert is a good friend of Mel Gibson from way back and if Zach really doesn't like him... I don't know, I just feel awkwardness watching these two together.
