At under an hour this JacktheZipper fever dream packs more heat, skill and cinematic pizzazz than most movies twice as long. If the production hadn’t been aborted for various reasons it might have become a cult classic.

Even as is there’s plenty to arouse is this loving tribute to grindhouse biker flicks, including a crazily intense orgy and fired-up fucking from Paige Morgan (as Creampuff, who get “turned into a ratty biker bitch”), Sasha Grey, Roxy DeVille, Shannon Kelly and nominal star Lanny Barby. It’s one hell of a salvage job — with a great non-sex turn from wild-eyed Brian Surewood and kick-ass music.  

Retailing: Short but potent — Zipper fans will love it.
