Trivia: This movie premiered in the US at the end of summer '75, following the blockbuster premiere of Jaws in June '75. When the studio created theatrical posters for The Rocky Horror Picture Show, one was a send-up with the caption, "A different set of jaws" under the big red lips.
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.
