As the slave cages are being unloaded on Mithra, the car and hovercraft from Logan's Run (1977) are visible in the background. Both resurface later as the pimp's and Zorn's vehicles.
Jason:
I don't mean anything by this but is there any particularly reason that he is black.
Roscoe:

When the prisoner cage is being hauled along the hangar, it's broad daylight, as is obvious in the matte shot with the outside view and in various windows and openings in the background. Wenn the cage is set down however, it's suddenly dark outside the hangar door.
