Michael Haneke's film FUNNY GAMES, one of the most disturbing and unqiue thrillers I've ever seen has been remade by Haneke himself with Naomi Watts and Tim Roth.
Here's the trailer: http://www.youtube.com/watch?v=Ec-70W_K77U&eurl=
A bleak, dark, scaborously funny thriller with third-wall breaking tendancies, Haneke's original film left me feeling uncomfortable all throughout, which certainly was his intent. You need a tough stomach for this film, and the remake looks like no exception.
Haneke also directed the thriller CACHE, which was pretty good as well.
