Well, there are actually 31 films inlcuded in this package from Mill Creek, each of the 12 discs are double sided.
One film is presented twice (The Pick Up), and two films that are said to be included in the collection are not (those are the films Carnival Of Crime and Lurkers), this adds the extra copy of The Pick Up and includes The French Quarter instead.
Still, even with the mistake, it's quite the bargain, since these films are quite obscure.
Many of them are Crown International Pictures.
This IS what included in the collection:
Drive-In Cult Classics - 8 Movie Set
Drive-In Cult Classics, Vol. 2
Drive-In Cult Classics: Volume Three
After Dark Thrillers
PS, Carvival Of Crime and Lurkers are found on this collection:
Cult Terror Cinema (12 Movie Collection)
which is also a great collection from Mill Cfreek.
