The Movie Transformation:
For one of his breakout roles in 1996’s
Courage Under Fire
, Matt Damon prepared for his performance as a drug-addled Persian gulf veteran by shedding a gigantic three-and-a-half stone.
Most actors tasked with such an overhaul take advice from a nutritionist to avoid permanent physical damage. Not Damon, who in the year following, had to embark on a series of medications to heal his depleted adrenal gland.
A diet of chicken, egg whites, broccoli and a baked potato every day is tantamount to a buffet in comparison to dietary procedures employed by other actors on this list.
However, he also ran twelve miles every day for four months.
Matt Damon Says:
“I went too far. I got sick and I wouldn't do that again because it was just too much. At the same time it helped the performance. I didn't have to act at all; I was a wreck. I was getting dizzy spells and hot flashes. I didn't say anything to anyone for a while because I was afraid I might be really ill.”
