The opening tape scene with Peter Graves was filmed on location at The Pike Amusement Park in downtown Long Beach, California. Seen in the background as Phelps was raised in the "cage ride" was the old General Telephone & Electronics (GTE) building. That building still stands (and is being re-purposed for use as housing in 2019), but the Pike Amusement Park no longer exists.
This is actually the second episode episode to use the new theme. The first is episode 5.3 The Innocents.
Early in the episode, one of the magazines in the rack on the plane is Elite, which was often used in the dossier scenes for Cinnamon Carter's photo during the first 3 seasons.
First episode featuring Sam Elliott in the opening credits. Peter Lupus is not in the opening credits nor the episode.
The map displayed in the police station is a map of Puerto Rico.
