Trivia: The voice of Mr. U.N. Owen on the tape is that of Orson Welles.
Trivia: In the generator room, Blore yells to Vera when she arrives; "Ms. Clyde! I told you to stay up in your room." He did, but in 1965. In this version (which uses almost entirely the same script of the previous cinematographic version) Blore did not meet Vera again at the bottom of the stairs, so he's referencing something that didn't happen - however it can't be ruled out that it just happened off-camera.
