No, but I have a copy of Suicide Club (AKA Jisatsu Saakuru) and it's been compared to Battle Royale. A friend of mine LOVES the very type of films I get squicked by - Hostel, Saw, etc. He sees them all and one of his favorite films is Suicide Club and even bought me a copy. UGHHHH!!

True, I didn't watch all of it but I just couldn't. It's set in Japan and suicide is the big fad in this film. Yeah, basically students think it's cool to commit suicide, usually in groups so they all do things like jump in front of subway trains in groups. *squicks*
