Now that Little Otik appears to have wrapped up at least an honourable mentions spot, I'll add my backing to;
The Devils Backbone
Battle Royale
Also gonna have one last throw of the dice on Shadow of the Vampire..... This is John Malkovich playing FW Murnau and Willem Dafoe play Max Schreck only Schreck turns out to be a real life vampire, specifically employed by the maniacal and obsessive Murnau, in order to bring his picture 'Nosferatu' to life. If that doesn't peek your interest right there I don't know what will! Its tongue in cheek dark humour, but it also has some weight behind it asking how far our creative minds will push boundaries to create art. Willem Dafoe puts in a career best performance and Malkovich is typically menacing as the obsessive Murnau. Fans of Nosferatu should love this movie, but there is enough depth for anyone to get something out of it.
Here's a short scene, give it a watch, this is real quality writing and acting on display;
Promise that's the last time I mention it!!
