Actors Who Risked Their Health Forever for a Role

Some actors go to extreme lengths to bring a character to life, pushing their bodies and minds to the brink. These transformations often come with serious health risks that can leave lasting damage, from physical injuries to mental strain that lingers long after the cameras stop rolling.

Hollywood celebrates these sacrifices, but the toll can be staggering, with some actors facing permanent consequences for their craft. Here are 20 actors who risked their health forever to deliver unforgettable performances, showing just how far dedication can go.

Christian Bale – The Machinist (2004)
