Recent?

Both LOTR films to date (and I suspect Return of the King later this year!)
Moulin Rouge
Pirates of the Carribean
Donny Darko
and many more...

Older?
Original Star Wars trilogy
Easy Rider
Goldfinger
The Italian Job
The Maltese Falcon
and many many more...

In general though I enjoy most things I see on the big screen. There are very few that translate to DVD or video but wide screen TV and Dolby 5.1 are making things beter:-)
