An actor's job is harder than it looks. It's not all Us Weekly covers and award show after parties at Elton John's house. Some of the most memorable characters in film history have been played by actors who have done a lot of very real, very hard work on their bodies before the camera even started rolling. Moreover, many of these actors go to both ends of the extreme, not only losing weight, but adding bulk of fat or muscle as well. This list includes actors who have made the biggest changes to their bodies from film to film.
What do you think about so much fluctuation in weight just for movie roles? Is it worth the potential damage to the actors' metabolism and organs?
