Method acting has produced some unforgettable performances, but it can also lead actors into some unusually intense territory. When performers become deeply immersed in a character, they sometimes keep elements of that role alive long after the cameras stop rolling. That can mean changing their appearance, adopting strange routines, refusing to break character, or putting themselves through genuinely uncomfortable situations for the sake of a performance. Some stories have become almost as famous as the movies themselves, especially when fellow cast members were left wondering where the actor ended and the character began. These fifteen examples show just how far some performers have been willing to go for their craft.
