Yea, it was called High Tension in the US.
I actually saw it at a test screening in SF a few months before it came out. My friend had tickets, asked me to go. I didn't expect seeing that gory ass movie though, lol. But I think it was a really well-made movie. Nice cinematography and everything. I think the US version had to get toned down, but the version we saw was the French one. I actually wound up buying a used French version of the dvd at a record store. Haven't re-watched it yet though.
Brotha Lynch would approve of the movie.
