You'd be hard-pressed to find an icon of cinema as instantly recognizable as Groucho Marx. The comedy legend, along with his brothers, crafted some of the most memorable films of the 1930s and made himself internationally famous. That's why his last role, in the insane 1968 comedy Skidoo, is so perplexing. Groucho plays "God," who is apparently some kind of Mafia boss living on a boat in international waters who tells Jackie Gleason to kill someone. Gleason goes to jail, does LSD and freaks out. We freaked out too.
