Another NBC actor that got super buff for the big screen is former Parks and Recreation
star Chris Pratt. "I'd gone back and forth, lost weight for Moneyball, got fat again, then trimmed down for Zero Dark Thirty
, then gained it all back again for Andy," Pratt recalled to Men's Health UK
. "That's when I saw Zero Dark Thirty and right after walking out I was like: 'I'm going to get in shape and I'm never going to be fat again.'"
