Usually Flintheart Glomgold is voiced by Hal Smith, but this time he's voiced by Hamilton Camp. The change in voice actors is especially strange, as Glomgold had been the principle antagonist for this four-part storyline and had been voiced by Smith in each of the previous installments. Adding to the oddity of the situation, Smith did appear in the episode as Gyro Gearloose, so he was clearly available.
Part of a movie-length, four-episode storyline. As with The Treasure of the Golden Suns movie-length event that launched the series, principal antagonists include both Flintheart Glomgold and the Beagle Boys.
There is seemingly no explanation as to how the normally dim-witted Beagle Boys are each apparently expert jet pilots.
