To land her role in Bridget Jones’ Diary, Zellweger gained enough weight to boost her from a slim size four to a size fourteen. To play Roxie in Chicago, however, she had to drop back down to a size six. It is amazing how these stars can control their weight with their diet and exercise levels.
While two of his films from the 1980’s were released only a week apart, D’Onofrio appeared drastically different in each. While for Full Metal Jacket the actor had to gain around 70 pounds, he quickly shed the extra weight to play a garage owned in Adventures in Babysitting.
Chris Pratt’s weight fluctuation has been constant for several years. For his role in Moneyball, Pratt lost 30 pounds in 2011. Within that same year, he put on 50 pounds for Ten Years. He then had to muscle up to play a Navy SEAL in Zero Dark Thirty, gain 60 pounds to play an obese lawyer in Starbuck, and then shed the extra weight to play the muscled Peter Quill in Guardians of the Galaxy.
