Oh.come now it's not like he was on stage doing Shakespeare. You know if you are going to put a mask on a guy I think you could get just about anybody to do it. Body language is something that could be learned by anyone in a few weeks with a decent acting coach. Take Darth Vader for example. He was the ultimate villain, and Prowse had no acting credentials yet he pulled it off better than anyone could have. Why? Because he was a physically imposing man, being an Olympic lifter. If they would have got a guy like Dennis Wolf then it would have been much easier to believe that this guy could kick Batmans ass. I had a tough time buying it. I don't think acting is rocket science. Even Arnold got some surprising acclaims from the critics for Stay Hungry. Which proves my point, film acting is not that difficult, stage acting, totally different.
On another note I recently saw Inception which had Tom Hardy in it. He looked totally different, no traps at all quite thin actually. I wonder how he did it. Hmm.
Why because star wars is a fucking movie made for children, horrible acting shit dialogue was pretty much a star wars staple.
Sure anyone in theory could spend a few weeks and learn the motions of each scene in the movie, but you don`t have a few weeks for each scene, things have to be done on the spot and they have to be natural, and no matter which way you do it, will bias the audience in one form or another.
Anyhow you might not think acting is rocket science, but it is in fact neuro science, acting is about tricking the brain so that what your seeing is both real and interesting at the same time. It`s a art, even Arnold one of the hardest working, socially dominate persons ever can`t compete with a 6 year old child actor.
