- A 'Preliminary Production Information Guide' from 7 June 1967 contained a synopsis (also reprinted in the final Production Information Guide from 29 January 1968) which named Woodrow Parfrey's character as "Dr. Octavius".  It is unclear if this was a simple error or if it referred to an earlier name for the character.
- Woodrow Parfrey also played Prefect Veska, Galen's cousin, in the opening episode of the Apes TV series.
