The battle of midway is done with captions to identify historical characters. Historically accurate in its major points, a subplot of an American flyer who is engaged to a Hawiian girl of Japanese descent has been added. This is the battle in which the previously undefeated Japanese fleet was stopped in a battle during which all damage was done by aircraft. The opposing fleets never saw each other.

This was the second film to be presented in "Sensurround", a special low-frequency bass speaker setup consisting of four huge speakers loaned by distributors to select theatres showing the film. This system was employed only during certain sequences of the film, and was so powerful that it actually cracked plaster at some movie theaters. "Sensurround" was employed in only three other films released by Universal: Earthquake (1974), Rollercoaster (1977), and the theatrical release of Battlestar Galactica (1978) (TV).

Commander Rochefort:
Bath? Hell, I don't know. What *day* is it?
