Not sure how these escaped my attention, but the following MGM Midnite Movies were re-released as quadruple features back in April of last year.
- The Land That Time Forgot / The People That Time Forgot / Panic In Year Zero / The Last Man On Earth
- Morons from Outer Space / Alien from L.A. / The Man from Planet X / The Angry Red Planet
- The Phantom from 10,000 Leagues / The Beast with 1,000,000 Eyes! / War-Gods of the Deep / At the Earth's Core
- Strange Invaders / Invaders from Mars / Invisible Invaders / Journey to the Seventh Planet
A couple of the titles have been OOP, and somewhat hard to find on DVD prior to this re-release, including The Man from Planet X and The Angry Red Planet (both of which I recommend to fans of vintage SF). There are a few stinkers in the bunch as well, e.g. Morons from Outer Space.
I ran across a couple of the above at a Target not too long ago, but haven't been able to find them again since. (And the last two are now showing as out-of-stock on their website.) Don't know if there are plans to release any of these on Blu-ray, but they can be streamed from various sources as well.
List of other movies in the Midnite Movies series. Anyone have the complete set?
Trailers for a couple other favorites in this set. You can't necessarily tell from the trailers, but both films have pretty nice scoped ~2.35AR cinematography, and both discs are anamorphic.
