plays a huge part in the movie business these days - how else would we conjure up fiery dragons and de-wrinkle our beloved veteran stars? Luckily, though, there are some things that never change: that is, actresses exposing themselves for, uh, "artistic" reasons. Now there's something that can't be ruined by computers, right? It's not like an actress can pretend to go nude, is it? If they're naked on the screen, then they're naked in real life, aren't they? And, I mean, you can always tell if it's a body double, because that never really looks right... Nope. Sorry. Everything you thought you knew about nudity in the movies is worthless. Fact is, actresses in the 21st century aren't quite as inclined to take their clothes off for money, and are turning to computers and new-fangled CGI techniques so they can save their dignity. I know: it doesn't make a whole lot of sense, because most of the time we leave the movie firmly believing that we saw them in the buff anyway. It's not like anybody is going to go home and check, is it? No matter: Hollywood has become really, really good at deceiving you. To celebrate that fact, here are 8 actresses who tricked you into thinking that you saw them nude. That's right... in these shocking cases, the sense of nakedness was purely illusion. Don't you feel just a little bit betrayed?
