Sundown: The Vampire in Retreat

This horror-western fusion features vampires residing in a remote, dusty desert town. In an attempt to peacefully co-exist with humans, they satisfy their bloodlust from a plasma-manufacturing plant. But when the plant malfunctions, a battle ensues between two vampire factions: one led by David Carradine, who plays the peaceful Count Mardulak; and the old-school bloodsuckers led by John Ireland, who plays a sinister vampire who considers the others as traitors to their predatory heritage. Jim Metzler, Bruce Campbell and Deborah Foreman co-star in this parody that's still terrifying.
