The version of the episode that was shown at the Landmark Theatre in Atlanta was unfinished. Two visual effects were missing.

The scenes on the algae planet were filmed in Kamloops, British Columbia, off East Shuswap Road. The location was chosen for its distinctive geological features like the hoodoos (tall, thin spires of rock of varying thickness said to resemble a totem pole). Kamloops (in south central British Columbia) is relatively close to Vancouver, where most scenes of the series are filmed.
