- Playing Against Type: The two male leads—George C. Scott as the emotionally repressed Archie and Richard Chamberlain, best known at the time as Dr. Kildare, as the Jerkass David.
- Unintentional Period Piece: It's very much a time capsule of San Francisco in The '60s (including cameos by Janis Joplin and The Grateful Dead), which gave it an added layer of meaning over the years.
- What Could Have Been:
- Henry Fonda was slated to play Archie at one point. Richard Lester wanted Lee Marvin.
- Robert Altman, who was still mainly known as a TV director at the time, was originally supposed to direct and played a big role in the development phase, but the studio decided he was too inexperienced to handle the film.
