MISTAKES/GOOFS

TRIVIA

• The first episode to be broadcast in color. Seaview is redesigned with only one set of observation windows and a hatch for the flying sub, although stock footage was used throughout seasons 2-4 showing the sub with three or six windows. New uniforms appear also as well as the flying sub. Over the course of seasons 2-4, there were six different flying sub models used for filming.
• The title is based on the biblical tale of the reluctant prophet swallowed by a whale as told in the book of Jonah.
