I've recently picked up:

The Pit and the Pendulum
The Fall of the House of Usher
The Man From Planet X

I am very pleased. What are some great discs in this series that I should pick up? What are your favorite MGM Midnite Movies?

Daniel, If you are into this genre, I can't reccomend this series enough. The transfers are usually excellent and are often even anamorphic. Get them all!!
There's a new batch coming out next month, see the earlier thread about it.

X: The Man With the X-Ray Eyes is one of the best films in the series, IMHO, and has a great commentary from Roger Corman. You also can't go wrong with any of the other Corman/Price movies.

Thanks for the suggestions. I don't know why I never picked up any of these before. Some of them have been out for such a long time; I hope they don't go OOP.

Killer Klowns from Outer Space

Great DVD, funny movie.

I really like this series too, but beware, some of the transfers are pan and scan versions. Attack of the Puppet People comes to mind. I think there are only 2 or three like that though. I also recommend the Price/Corman movies, Fall of the House of Usher is a favorite of mine.
