If the money was right, would you be willing to lose alot of weight?  Some of Hollywood's most famous actors have gone to extremes to lose weight for certain roles.  Despite the big paycheck, it sounds pretty miserable.

Matt Damon, who is an extremely successful actor, lost forty pounds for his role in 'Courage Under Fire.'  What food did he miss?    He told People he really wanted cheeseburgers while dieting  for that 1996 movie.

Christian Bale, one of my favorite actors, had to lose sixty-three pounds to play an insomniac in the 2004 movie 'The Machinist.'  His weight loss secret?  He ate one apple and a can of tuna a day.

Matthew McConaughey plays a man with AIDS in 'The Dallas Buyer's Club.'  His trick for losing thirty pounds for the role was drinking lots of tea and he told People he feels "pretty good at this weight."

To get that look for his role in 'Castaway,' Tom Hanks shed fifty pounds and according to People, said it simply took "time and discipline" to do so.

A liquid diet for nine weeks was how rapper 50Cent lost fifty pounds to play a cancer patient in last year's 'All Things Fall Apart.'

Of course, sometimes actors and actresses have to gain weight for roles too.  Renee Zellwegger did that to play Bridget Jones and being very fit, she found it a challenge.
