Talk about immercing yourself

I've always thought that method acting was a bit extreme. Granted, I'm sure that it really does help build a character, but really, is it necessary to change yourself when you're off the set? How weird would it be if you had a friend who was normally really happy go lucky kinda guy/gal, but because they're playing a role htey're playing, they're now Debbie Downer? Although, that could prove to be quite the hit at parties... ;)

Where do you draw the line?

Phoenix Takes Acting As Heavy Drinker Cash Too Far

Joaquin Phoenix developed an alcohol dependency while filming his role as Johnny Cash in the new movie biopic Walk The Line. Country singer Cash, who was a renowned drinker, prompted actor Phoenix into increasing his alcohol intake for a better portrayal of the character. Gladiator star Phoenix, 30, realized his problem was getting out of control and in April checked himself into a rehab clinic when filming was over. He tells London magazine Time Out, "It was then that I became aware of my drinking. I wasn't an everyday drinker but didn't have anything else to do, anything to hold me down. I was leaning on alcohol to make me feel ok. That's what it really was."
