I recently finally watched the movie Audition.  I first learned of this movie from links from the Saw movies.  Thank goodness for Netflix online!

Anyways, I read some comments and such on the movie (don't go to the Wikipedia page for Audition because the whole movie is spoiled there).  Eli Roth, Rob Zombie, and John Landis all say this movie extremely creeped them out.

I would suggest just seeing this movie.  Don't watch any trailers or anything.

Just be prepared to be scared out of your mind.  I actually closed my eyes at one point!  There also were a few other times when my eyes opened wide and was like "WTFUDGE!!!"

Watch it.  If you're a man, make sure you don't watch it with a girl, because you'll look like a total wimp!!!
