Mario Van Peebles (Captain William Clark) is the son of the director Melvin Van Peebles. While Melvin directed Mario in a TV movie and some feature films, this was the only TV episode for which he's credited with directing him.
According to the recovered visual record, Captain Clark and Dr. Dufour evacuated the UNAS Meridian on June 20, 2037, exactly forty years after the date of the original broadcast.
