A special features segment included on the official DVD release for Roxy Hunter and the Myth of the Mermaid revealed that the "Roxy Hunter Triggerification Process" song segment, portrayed in the film as a spontaneous song, actually took a great deal of rehearsing beforehand, and multiple scene retakes. Actors Aria Wallace (Roxy Hunter) and Julian Richings (Mr. Tibers, the librarian) both considered the scene a lot of fun, but difficult. Richings had to alter his own voice during parts of the song to mimic different regional accents, and both actors had to get the song's rapid lyrics completely correct from memory.
