The only known copy of this movie to exist is available for viewing in the archives at the Paley center in New York City. It can only be viewed within the library archive and cannot be checked out. It has never been marketed for mass release.
The cast includes three actors from the main cast of the following year's classic original version of O Planeta dos Macacos (1968)--Roddy McDowall, Maurice Evans and James Daly--all of whom would play ape characters (Cornelius, Dr. Zaius, and Dr. Honorious, respectively) and all of whom would participate in a tense kangaroo court sequence reflective of the Joan of Arc story.
