The final full-length Flintstones project for the original voice of Wilma (Jean Vanderpyl), Bamm Bamm Rubble (Don Messick), and longest running voice of Fred Flintstone (Henry Corden, the second Fred from 1977-2000). Jon Stephenson, the original voice of Mr. Slate, would later voice the character in The Flintstones: On The Rocks. Whereas death is usually the cause of a replacement actor for the Flintstones (with the notable exception of Betty Rubble, who had two different voices in the original series, and has been voiced by a different actress in virtually every new Flintstones encarnation), Corden was not asked to return for that project, making this the longest running Fred and Wilma's swan song.
The play is narrated by a man named Mr. Brickens. This is an obvious reference to Charles Dickens, author of the original version of "A Christmas Carol".
The final Flintstones film to be created and produced by the original Hanna-Barbera productions.
For obvious reasons, Scrooge's nephew "Fred" is re-named "Ned" in this version.
Philo Quartz originated in the television series The Flintstone Kids (1986). This special marks his only appearance as an adult.
