There are no credits at the beginning at the film, which was extremely rare for a 1960s film. They all appear at the end of the film.
The Columbia Pictures logo at the end of the film is in an Art Deco design.
In the closing credits, the names of Terry Chambers, Mike Burns, Esther Shepard, Kristine Helstoski, John Hoffman, Linda Weaver and Jim Hanley and the characters they play are reversed.
At the end of the closing credits, the laugh of the mermaid who was kissing The Monkees in the first scene is heard.
The film ends with the film strip breaking down.
