Filmmaker Stuart McGowan led a varied career, directing westerns (including 134 episodes of television's Death Valley Days), war movies (Tokyo File 212), childrens' films (Mr. Too Little), and this 1969 curio, aka The Passion Pit, which stars actual twins Robert and David Story in the role of, uh, actual twins. One's a psychopath who stores his victims' corpses in the ice house where he works, the other's his honest cop brother investigating the cold case when they're not dancing "The Scrub" along with Johnny Wadd at the oh-so-groovy Magic Mushroom. Also with Jim Davis (Jock Ewing from Dallas), Scott The Mighty Gorga Brady, Otto Preminger vet Kelly Ross, the "British Marilyn Monroe" Sabrina, and Jennifer Aniston's mom.
