WTF Happened To The Return Of The Living Dead? WTF Happened to this horror movie?!

When Night of the Living Dead released in 1968, it spawned two very different zombie series. First, was director George A. Romero's Dead franchise, which continued with Dawn, Day and Land (amongst others we won't mention here out fear of them being remembered). Then the other writer of Night, John Russo, had a series of his own that would fall under the Living Dead moniker. While his involvement lessened by the time the movie was actually made, we were left with an insane comedy/horror hybrid...
