Surprised this hasnt been remade yet
I swear if they havent thought about already, they will. I am not an advocate of remakes whatsoever (barring very very few exceptions), but I just see this as perfect remake fodder for the US especially since its done by a pretty edgy Spanish director. Japanese and Spanish titles have been remade the most so far...
(and yes, I am going to go knock on some wood now)
