Trivia: Before the witch trial, you can see Sir Bedevere tying coconuts to a swallow, no doubt to test the theory people argue about elsewhere in the film.

Trivia: Although Joan Sims plays Patsy Rowlands' mother in this film, Sims was only four years older than Rowlands.
Suggested correction: There was only eight months between the two actresses.
Wikipedia has Patsy Rowland's date of birth wrong. Patsy died in 2005 and in a 2005 article by The Guardian, the article list her age as 71. This would put her birth year 1934, not 1931, which is also confirmed at the end of the article.
Trivia: What was Mr Mason's first name?
Trivia: Lina Wertmuller became the first woman to be nominated for an Academy Award for Best Director with this film.
Trivia: Science-fiction author Harlan Ellison wrote the original novella "A Boy and His Dog" in 1969, and director L.Q. Jones wanted Ellison to also write the screenplay for this 1975 film. When it became apparent that Ellison could not provide a screenplay (due to "writer's block"), Jones co-wrote the screenplay. In a DVD commentary decades later, Jones said that Ellison was pleased with the finished screenplay and movie except for certain dialogue. Ellison was especially offended by the last line of the movie, spoken by the telepathic dog, Blood: "Well, I'd say she certainly had marvelous judgment, Albert, if not particularly good taste." (This grisly line alluded to Vic and Blood eating Quilla June Holmes, the female love interest, in an act that happens off-camera.) Harlan Ellison said it was a "moronic, hateful, chauvinist last line, which I despise."
