The once-ripped gladiator packed on the pounds for his 2008 spy thriller Body of Lies. Russell gained a beefy 63 pounds by eating lots of junk food. The actor gorged on cheeseburgers for breakfast, and revealed in an interview with Access Hollywood, "If you want to put on weight, you just elect to live a sedentary life."
But Crowe gained so much weight he had to "rock back and forth to get out of his car." Taking off the pounds wasn't easy - the actor hired a nutritionist and hit the gym daily.
