This is a gem of disaster from the waning days of MGM. It seems there was a decision that the only way to beat the loss of ticket sales to television was to out-stupid it. With a logic straight out of "Rocky Jones" and a script from Ignoramus Inc., this film busts the audience's tolerance and drives over it.
This film must have been dumped by MGM towards the end of production. Listen to the sound. All the scenes at the home base of the sub team have incredibly bad sound for a major studio release. They must have decided that it wasn't worth the cost of rehiring the actors to re-dub their voices so they left the terrible sound.
The guinea pigs were so embarrassed by this film that they never acted again.
