The 42-year-old Oscar-nominated actor said that dieting began to take a toll on his body after he shed the pounds for his latest role in the film as a transvestite who is addicted to drugs and dying of AIDS, reported Contactmusic.
"It does take its toll and it's not something I will ever do again. It's a really hard thing to do to your body. When you do it over a short period of time it's incredibly brutal," he said.
"This time, I was playing someone who was not only addicted to drugs but also dying. When you lose weight it's not only about how you look, it's how it affects you as a person, and your performance, and it changes so much about how you are. The fragility that all provides was essential to the part.
