The Fighter - 9/10
Awesome movie. Felt like I was watching a classic. I'm a big fan of Bale and Wahlberg, and the acting was great all around. I've never cared too much for Amy Adams, but she did a great job too. The only thing I was scratching my head about was Micky's (Mark Wahlberg's) weight which was 146 lbs. There's just no way.
Micky Ward was only like 5'7"-5'8", so weighing only 146 lbs is very plausible. Floyd Mayweather is about the same height and weight and pretty much has the same looking bulk. And plus, 146 was probably the limit (or close to) for his weight class anyway, so he couldn't be heavier.
Why does Christian Bale have to gain/lose so much weight in all of his roles??? The dude is jacked in both Batman films, smaller than anyone I know in the Machinist, and about my size (but more awkward shaped) in The Fighter.
Commitment.
From a super hero to a crackhead. That would require losing weight and vice versa. What he's doing definitely ain't healthy, but hey, as I said, the guy is committed to his work.
