Except for a cameo by Carl Wilson, the guest appearance by The Beach Boys is stock footage of the band performing "Barbara Ann" and "Fun, Fun, Fun."
The role of Anne Perry was played by Marcy Lafferty, who from 1973 to 1994 was the wife of William Shatner.
The second time William Shatner stars with a character who is a blind woman. The first time was Is There in Truth No Beauty? (1968)(#3.5). Both times, he doesn't know at first that she is blind, he discovers that fact afterwards.
One of only two episodes where anyone wears sunglasses, namely Anne Perry. The other is the title character in Big Foot (1982)(#2.5).
