My list of obscure movies include:
Pulp Fiction - absolutely a must see if you haven't
Natural Born Killers - the main characters (Woody Harrelson and his female co-star - forgot her name) are certified crazy!!!!!
The Usual Suspects - have to watch it again, it's been a while
Reservoir Dogs - I have the tape, but have yet to find the time to sit down and actually watch it
Very Bad Things - starring Cameron Diaz and Christian Slater. Totally weird from beginning to end. Another must see!
Cruel Intentions - starring Reese Witherspoon and Sarah Michelle Gellar (sp?)
