Horror film director and low-budget auteur Frank Henenlotter has made a career out of films such as Basket Case and Brain Damage that suggest a careening busload of sophomoric practical jokers trying to win a derby of bad taste and outrageous gore. But no matter how many face-palm moments fill his pictures, there’s always a spark of intelligence, charm and heart behind the “no-joke-too-tasteless” ethos of his cinematic water balloons. His 1990 epic of lawnmower mayhem, exploding trollops and love beyond dismemberment, Frankenhooker, may well stand the test of time as his greatest achievement. See it with someone you love — just make sure they haven’t eaten first. And return the next day for Saturday’s Body Count Indie Horror Film Festival and Masters of Horror marathon, starting at noon.
