Fox was promoting a new game based on Planet of the Apes. They hired these models to be held prisoner. The ape-men themselves were surprisingly realistic; it looked like they used the same makeup and masks from the film. (Periodically when I'd walk by, I'd notice the women staring forlornly out of the cage, hitting around the bars with a stick, looking bored. It honestly seems like you'd get bored sitting in that cage for most of three days.)
