I'm noticing lately that there are a lot of great movies that are not out on DVD yet... what's with that? Here's just a short list of movies I would buy if they were available:

Star Wars Trilogy
White Nights
The Turning Point
Some Came Running
Two For the Road
What a Way to Go
A Night at the Opera
Duck Soup
Can-Can
Help!
Imagine: John Lennon

That's all I can think of right now... but I'm sure there are more.
