"Nagel" is an anagram of "angel," which is basically what Nagel is in this episode.

This episode was remade as AIO video #9, with the same name. The cartoon version has Dylan Taylor instead of Jimmy Barclay, a few variations, and the sea battle scene cut completely.

When Jimmy and Nagle are in the space ship, Jimmy asks if his enemy is "Grimmulin", which sounds like "Rommulin" from "Star Trek: The Next Generation." Also Nagle uses "phasers" — Star Trek weapons.

The villain "Grim" in the final fight in space sounds a lot like Darth Vader (a lot of holding the "s" sound in sentences) and shares some of his lines like "It is useless to resist," and "...face your destiny." The entire scene sounds very similar to the final confrontation in The Empire Strikes Back.

The title of this episode is a reference to a George Gershwin song by the same name.

It's possible that the second scene with Nagle was inspired by the James Bond movies.
