Claude Rains makes his first of several guest appearances in this episode. He had previously co-starred in Alfred Hitchcock's classic 1946 suspense thriller Notorious.

Bradbury's story was later adapted as an episode of The Ray Bradbury Theater.

Virginia Gregg would go on to play another disembodied voice belonging to a fantasy woman, in Hitchcock's Psycho.

Alfred Hitchcock: (out of focus) Good evening. (comes into focus) This misty bit of ectoplasm forming on the inside of your television screen is one Alfred Hitchcock, coming to you from across that great barrier that divides the quick from the dead: the Atlantic Ocean. I have materialized for the express purpose of warning you that during tonight's séance, you will witness a playlet entitled: "And So Died Riabouchinska." Oh, yes. Before we have our play, I would like to make an announcement to those of you who can't stay until the end. The butler did it.

Alfred Hitchcock: That was pleasant. It also reminded me of my youth. When I was once a part of a vaudeville act called: "Doctor Speewack and his Puppets." But I never cared for Doctor Speewack. He thought he was better than the rest of us. But so much for tonight's entertainment. Until the next time we return with another play, good night.
