From Dusk Till Dawn 3: The Hangman's Daughter (2000)

This straight to video feature is a far cry from the first film, but leaps and bounds better than the second. Actually, this prequel pretty well follows the story line of the first one, only this one is about the origins of Santanico Pandemonium. It is set back in the old gunslinging west and ends up in a brothel where the vampires live. Check it out if you liked the first one. (Story written by Robert Rodriguez)
