Martyrs is a fantastic movie. I've recommended it to people and then they make a face when I say to watch it with subtitles. Fuck dubbing and fuck the English remake. Apparently Pascal Laugier came out with a new movie a few months ago, haven't seen it yet. Ghostland. It got good reviews but the dialogue is in English so some people found that aspect kinda clunky.
Gaspar Noe... Irreversible. That rape scene was about eight and a half minutes too long.
I can't find an article anymore but there's a shitty movie called Slaughtered Vomit Dolls, and supposedly the director was having an incestuous relationship with his semi retarded sister or something? I remember reading that she killed herself in a bath tub just like a character from the movie.
Also, A Serbian Film. Fuck that.
High Tension is pretty decent, It gets bonus points for introducing the killer in the funniest way I've ever seen.
