I'm suprised nobody has mentioned this!

Well, maybe some people have, I just havn't gone though every post on this board lol but back to the subject at hand...Battle Royale or more like Battle Royale 2. When I first watched BR and BR2 it was Wedlock that came to mind and their is no doubt in my mind this was inspiration considering the whole idea of exploding neclaces are practically identical.

It's been years since I've seen Wedlock and I used to have it on VHS but from what I remember it was one of Rutger Hauer's best films.
