Acting isn't as easy as some might think - it takes years of training, dedication and talent to make it to the top, and you only have to turn on the television during the daytime and watch a few soaps to realise just how terrible some acting really is. Different actors take different approaches to getting into character and embodying the roles - some use the classical acting model of Stanislavski, using bodily and vocal expression in conjunction with imagination and improvisation, while others prefer the more hardcore method acting approach, drawing upon a range of techniques which immerse them fully in the character, a variation and expansion of Stanislavski's approach adapted by Lee Strasberg for American actors. While often the results are awe-inspiring performances in which the actor seems to literally embody the character they're portraying, the cost for such authenticity can sometimes be high, placing emotional and physical stress on the performer above and beyond the levels most people would be able to tolerate. Here are ten actors whose commitment to their roles was certainly in no doubt - but the lengths they went to certainly suggests they took it all way too seriously.
