Have not seen this film in years and it was a great experience seeing this film and the great veteran actors who made this into a great WWII story. Cary Grant, (Capt. Cassidy) plays the commander who manages to take his submarine right into the backyard of the Japanese Nation. John Garfield, (Wolf) plays a great role who charms the crew with his tales of all the women he met along with a great deal of exaggeration. Alan Hale, (Cookie Wainwright) was a cook on the submarine and was able to give a great deal of comedy to his role as the chef. This film will keep you on the edge of your seat when the sub comes under fire from the Japanese Destroyer's while one of the crew is having surgery by a man who knows nothing about appendicitis. Dane Clark, (Tin Can) gave a great supporting role in this film and this film started a great career for Dane in Hollywood. Great film, don't miss it, you can see this film over and over.

This engrossing film takes place on a submarine bound for Japan to do a lot of damage. It primarily deals with the personnel on board. Led by Cary Grant, a tough, but real family man, this film goes on to explain various situations, including an emergency appendectomy done by a pharmacist on board the ship.

John Garfield, as Wolfie, steals the show. He always talks of his adventures with women. In one scene, he talks about this with the music of Cole Porter's "Night and Day" as a backdrop. Ironically, Cary Grant is not in the scene. Two years later Cary was in a major biographical-picture with that title about the great Porter.

Garfield and his guys do their work on land quickly to deliver valuable information that will aid in the bombing. That bombing as well as the bombing that the sub is subjected to is very realistically done.

Grant talks of something that we can relate to today. He speaks of young Japanese children being taught at a young age to hate. It's so many years later and we hear the same thing about young Palestinians. War comes from hatred.

Captain Cassidy (Cary Grant) leads his submarine USS Copperfin on an important mission. He delivers meteorologist Lt. Raymond to Tokyo Bay to gather weather intelligence for the Doolittle Raid.

This is an early submarine movie. It has the great Cary Grant in the lead. It spends too much time with the crew's stories. At the very least, it has the setting that future movies look to as a baseline. While they do tip the whole set, it's not quite the extreme angles that really exaggerate the tension. It needs a tighter setting to break out the claustrophobic paranoia. The miniature work is fine. This lays out the blueprint for a submarine thriller which those who follow are able to improve upon.
