- Prop Recycling:
- The Anderan Senator costume is a reused Ebonite suit from "Nightmare". The Senator appears only in shadow in an attempt to hide this as much as possible.
- One of the Calco heads got reused in the Star Trek: The Original Series pilot "The Cage". Considering the similarities between that episode and "Fun and Games" (humans finding themselves at the mercy of a powerful but decadent alien race), it feels oddly appropriate.
- What Could Have Been: According to David J. Schow's The Outer Limits Companion, the role of Mike Benson was offered to Clu Gulager, Rip Torn, and George Segal before Nick Adams finally accepted it.
