Contains:
The Atomic Brain (1964)
The Brain that Wouldn't Die (1963)
Carnival of Souls (1962)
Night Tide (1961) featuring Dennis Hopper

The first two are Mystery Science Theatre 3000 material. In fact, I think that's where I saw The Brain that Wouldn't Die the first time. But that doesn't mean they are bad in the sense of not being worth watching. Sort of like Plan 9 from Outer Space...so bad it's really good.
