One of the truly strangest films ever made, this delivered a hit to the careers of Robin Williams and Robert Altman that followed them for years. It's a musical featuring hash-soaked folk-rock tunes from Harry Nilsson, delivered by non-singers like Shelly Duvall, and it still manages to be catchy with songs as ridiculous as "Blow Me Down." A special MVP goes to "Mr Hand" himself, Ray Walston, as Poopdeck Pappy, one of the greatest characters in comics.
