Some actors take their transformation to the next level, pushing their bodies and minds to the limit so that they can fully embody their characters. CGI, prosthetics, and makeup can help these stars really show commitment to the craft.
Whether it’s packing on muscle, shedding dozens of pounds, or sticking to bizarre diets, these have to be some of the most extreme celebrity transformations we’ve ever seen.
From the acclaimed actor who gained 100 pounds between roles to the beloved actress who survived on just one type of food during filming, these are some of the most jaw-dropping, commitment-fueled transformations in Hollywood history.
These transformations were achieved under professional supervision and for artistic purposes. Extreme dieting or rapid body changes can be harmful and should not be attempted without medical guidance.
