Among Hollywood’s various failed attempts to cash in on the LSD craze of the late 1960s, Otto Preminger’s Skidoo (1968) stands out as quite possibly the strangest of the bunch. Imagine a zany Peter Sellers comedy about organized crime, featuring psychedelic visuals and bits of Marat/Sade done up in hippie garb, starring Jackie Gleason, Carol Channing, Frankie Avalon, Burgess Meredith, and Mickey Rooney, with Groucho Marx playing a character named “God.” They even got Timothy Leary to appear in the trailer, telling “every young person in the country” to “turn on Mom and Dad by taking them to this movie.” “Dated” doesn’t even begin to capture the marvels of this trainwreck.
