There is a picture online of Williams from this past July. It was the thinnest that I've ever seen him. He looked a good thirty plus pounds lighter than we're used to. I'm not sure if the weight loss was for a role, but I know that people suffering from severe depression often lose their appetite. If the weight loss wasn't for a role, it looks like Williams' depression also took a toll on his body.
Weird question, but Williams always looked like a stocky, fairly powerful man. Not fat, just sturdy. Barrel chest with thick arms and legs. Williams' character in Good Will Hunting, Sean, tell Will that he benches 285. Do you think that Williams used his real bench figure?
