See, it's a weird thing because a big part of the actor's what-have-you is their image, if you're a Halle Berry or another established actor, you've got this image to maintain and you don't want to damage yourself in anyone's eyes and you don't want to cheapen yourself, so the clothes stay on and the role choices become rather conservative when the reality is that flexibility is the key, and I don't mean being flexible means getting your kit off, it means taking bigger risks and doing things you wouldn't have considered otherwise, which I think is why so many people become actors in the first place. And I think the proliferation of cheap but high-quality production and distribution technology is making that ability easier (think of all the big actor names doing things for Funny Or Die).
