This has a great introduction by Fleet Admiral Chester Nimitz. Not often seen speaking, Navy buffs will like seeing the Admiral introduce this film. He talks for about 2 minutes, explaining how he approved the orders for this real life event in WW II.
Columbia Pictures released this film on a double bill with The Tall T (1957).
The co-author for the screenplay was credited to Raymond T. Marcus, who was in fact blacklisted writer Bernard Gordon. Ironically, the movie starred Ronald Reagan who was more-or-less a proponent of the blacklist.
