That sucks! Of course now I can't remember any... so here's a few for starters...
Garden State with Zach Braff (wrote and directed as well) and Natalie Portman. Welcome to Collinwood, a Coen-esque caper.
Life is Beautiful - fantastic, subtitled though! Glengary Glen Ross - from a Mamet play, huge cast! Rushmore - Wes Anderson. Rebecca - overlooked Hitchcock!
Pi - Darren Aronosky - chaos theory, Jews and Wall Street, quite dark but I love it... not to everyone's taste.
In Bruges, hilarious. Wonder Boys, Robert Downey Jr is superb - these are quite well known, but possibly overlooked.
If you haven't seen them yet, Iron Man, just good fun... The Hangover, very funny!
If you think it's going to last, The West Wing or The Wire box sets... although they will leave you feigning illness. I actually think everyone should watch these two anyway!
