I have about 50 DVDs... take a wild guess

seems to me though, that unless you obsessively collect everything, you are bound to not like at least a couple big name actors or directors and not buy their movies

Are we forgetting that Julia Roberts was in the very watchable remake of "Ocean's 11"? And in "Confessions of a Dangerous Mind"?

Inany case, I'm missing a number of great films and directors. I have no Ozu, no Eisenstein, etc. I'd also like to get a complete Hitchcock collection.
