This film was originally released as Curse of the Screaming Dead then Troma picked it up and rebadged it Curse of the Cannibal Confederates. I bought both videos. Both are bad.
What is interesting is how a company like Troma repackages the film. They re-edit the film placing zombie footage from later in the film in place of the original front titles, and anywhere else the film seems a little slow. Unfortunately the zombie footage isn't good.
It also appears that they play entire reels in a different order. A recipe for disaster in most films but in this one you really can't tell.
Both films are bad and no amount of re-editing could save it.
I don't recommend watching these films back to back or at all, but if you must, do what I did, watch them simultaneously and marvel at the futility of it all.
I think the only positive thing about this film is it was made by a group of people who weren't filmmakers (it appears) but just a bunch of friends, more power to you.
