http://us.imdb.com/Title?0108399  -  Info about True Romance.. really, you must see it.. lol
There are a few great ones mentioned .. I thought Das Boot was an excellent film.  I've seen the German (subtitled) version and an american version.  The original is by far the better one.  It has a truly creepy feel to it...I felt suffocated near the end.  LOL
American Psycho, Desperado and Memento are also favorites of mine.
And I LOVED  Home For The Holidays with Holly Hunter and Robert Downy Jr. - If you have a wacky family(which I think most of us do), you'll appreciate this movie 
OK.. has anyone seen this independent film called  Happiness?  It was funny, interesting and disturbing all at once.   A must see.... well, if you don't mind being a bit disturbed.. lol   Here's info
