Actors must be masters of their craft in order to gain any kind of respect in Hollywood. They have to go the extra mile and show their insane commitment to their roles in order to shock audiences. Sometimes, this means that they need to rapidly gain muscle, lose weight, gain fat, lose muscle…you name it.
Their body is as much a part of the role as their acting is, so they must look the part. But sometimes, the transformations are so ridiculous, they”re almost hard to believe.
