Shrink Rap

Actor Mark Ruffalo.tells The Advocate that even  as he prepares to play Bruce Banner aka The Hulk in the 2012 superhero team-up film The Avengers "no one has asked me to shave my chest yet, thank God. They want this Hulk to be as close to me as possible. I'll be playing him in motion-capture, so this Hulk will just be a bigger avatar version of me. As they're modeling him, they're using many of my own features, down to my scars and wrinkles. He will have body hair, but I don't know to what extent."

Meanwhile as we know his co-star Chris Evans worked out like crazy to beef up for his role in this summer's Captain America:The First Avenger But when we first meet Steve Rogers in the pic he is rather puny looking,

Evans told USA Weekend: "It was a crazy process doing that stuff. They went back and forth on the type of technology they were going to use. Initially, they were just going to do body shrinking, and then they thought, 'Well, maybe we can get another skinny actor and put Chris' head on it,' and I really, really was against that. I said to Joe [Johnston, director], 'Look, I know we want this to look good and this effect to not be distracting from the film, but it has to be my performance. I don't want to share this. Your body is a huge piece of the acting puzzle, and I don't want to have somebody else's body tell the story that I'm trying to tell.'"

He adds, "So they did some tweaking and they did a bunch of tests and we went back to the initial plan to shrink my body. Anytime my body's completely still, if I'm lying on that bed or if I'm sitting in a chair not moving, it was easier for them to put my head on a smaller body. But anytime there was movement or action or acting involved, Joe and I were pretty adamant about saying, 'Look, you've got to shrink me down.' And they did. I haven't seen the film yet, but I've seen a couple different scenes of the shrunken stuff and it looks amazing."
