Malcolm Danare, Kevin Dunn and Michael Lerner reprise their respective roles as Dr. Mendel Craven, Major Hicks, and Mayor Ebert from the movie.
The voice of Elsie's ex-fiancÚ Lawrence Cohen in "Birds of Paradise" is Tate Donovan, who also voiced the title character of Disney's Hercules. Which becomes a bit Hilarious in Hindsight when one considers that as Hercules, he was beating up giant monsters with little problem, while as Lawrence he can barely take care of himself against a giant flying lizard that was the inspiration for Quetzalcoatl.
Keep Circulating the Tapes: For quite some time, the only releases this show had were two DVD releases that only had a few episodes, one in particular covering the "Monster Wars" trilogy, as well two VHS tapes. Netflix later got the rights to stream all 40 episodes (which included two episodes that never aired during its original run), and now to coincide with Godzilla (2014), Mill Creek Entertainment gave the entire show a 4-disc DVD release.
