Trivia: Prince of Darkness
- Fan Nickname: Friar Loomis for Donald Pleasence's character.
- Hey, It's That Guy!:
- Playing Against Type: Donald Pleasence was primarily known for playing coolly cynical, even cruelly manipulative characters, but his priest here is horrified at the deception the church has played on the world. Similarly, Victor Wong's roles are typically very religious or otherwise steadfast in their ways, but Birack is open-minded and accepting of wildly different perspectives.
- You Might Remember Me from...: Alice Cooper plays one of the possessed hobos (his character is called "Street Schizo" in the end credits).
