Writer Paul Krassner published a story in the February 1981 issue of "High Times" magazine, relating how Groucho Marx "prepared" for his role in the LSD-related movie by taking a dose of the drug in Krassner's company, and had a moving, largely pleasant experience. In his 1976 book, "The Groucho Phile", Marx (who, having abandoned his trademark greasepaint mustache twenty years prior for "You Bet Your Life", returned to using greasepaint for this film) commented that both the movie and his performance as the mob boss God were "God-awful!" Most of the rest of the cast and crew, though, apparently had no familiarity with the drug; in a later interview, Nilsson recounted that he simply pretended to be drunk for his role (his own subsequent LSD experience inspired "The Point!", a 1970 animated movie Nilsson wrote and scored).
