I wouldnt call acting a job - its a pleasure. I love getting to play different characters, getting to play dress up, and getting paid for it.
Just because the character listens to an iPod and wears black nail polish, she's goth. That was just a misused word
If the character should be nude in the scene and it makes sense and I trust the person making the film then I don't see a problem with it. I certainly don't want to be involved in anything that is gratuitous, but I don't think the human body is something to be ashamed of. Every other person on the planet has the same parts as I do.
