As a feat of endurance, I think that Christian Bale losing
weight for The Machinist was more of a challenge that how ever
many burritos Clooney had to eat to gain 50 lbs.The Machinist shows Christian Bale as life-threateningly thin.
And while watching it I wonderd if it were some photographic
trick. It wasn't. When asked about it in the "making of"
portion of the dvd, Bale said, "I just stopped eating."
Between these other things that I've mentioned, I also view
some documentaries.
"Paperclips" was extraordinary and moving. I mention this because
I've actually seen it on the shelf at the vid store.
