- Enforced Method Acting: Christopher Lee had an extreme phobia about spiders, so in The Hound Of The Baskervilles, when the tarantula is crawling up his arm, he's not really "acting" terrified.
- Nastassja Kinski was having trouble coming up with tears for a scene in To the Devil... A Daughter (she was very young and inexperienced at the time), so costar Richard Widmark straight-up slapped her in the face to get her crying. (Kinski, for her part, never bore him any ill will and said later she knew he was just trying to get a good performance out of her, and that he taught her a lot.)
- Fake Nationality: About one million times. Basically, this would show up in any movie set outside England, and even some set inside it.
- Hey, It's That Guy!
- Missing Episode: Hazel Court allowed a topless scene to be filmed for 1959's The Man Who Could Cheat Death. It was only included in prints distributed outside the U.S. and England. It appears this footage has been lost forever, although Court did put a still from it in her autobiography. (Let it never be said that she didn't appreciate her fans.)
- The Other Darrin: Jessica Van Helsing is played by Stephanie Beacham in Dracula A.D. 1972 and Joanna Lumley in The Satanic Rites Of Dracula .
- Somewhere, a Palaeontologist Is Crying: Dinosaurs and man alongside each other in One Million Years BC and When Dinosaurs Ruled the Earth. Creatures the World Forgot shows why the trope is necessary — if you think being slightly more realistic makes it better than the others, seek medication.
- Troubled Production: Blood From the Mummy's Tomb, adapted from The Jewel of Seven Stars; Peter Cushing was cast as the lead but had to drop out after a single day's filming due to the hospitalization of his wife. Then five weeks into production (with only one week to go), director Seth Holt had a heart attack and died (some reports saying this was on set) and was replaced by Michael Carreras. On top of all that, star Valerie Leon was devastated when she was told she couldn't attend Holt's funeral.
- What Could Have Been: If the film hadn't been a financial disappointment, there were plans to do sequels to Captain Kronos Vampire Hunter, with Kronos traveling the world (and even through time) to fight evil. Director Brian Clemens, in his DVD commentary, said that if that had worked out, he probably would've had to change the character's name to "Captain Buffy".
- "Taste the Blood of Dracula" originally wouldn't have featured Dracula at all. Instead, the villain would've been Lord Courtley (played by Ralph Bates), a follower of Dracula who would've been transformed into a vampire. When the film's distributor objected, a reluctant Christopher Lee was brought back.
