A 1959 comedy starring Creator/CaryGrant and Creator/TonyCurtis and directed by Creator/BlakeEdwards concerning the manic maiden voyage of the submarine ''Sea Tiger'' in the early days of WorldWarTwo.

The movie begins with Rear Admiral Matt Sherman (Cary Grant) making a sentimental visit to his first command, which is due to be scrapped. He goes down to the empty Captain's cabin, opens the old log book and begins to read. Cue flashback to December 10th 1941. The ''Sea Tiger'' is sunk at dock and the crew works frantically to jury-rig sufficient repairs to make the run from the Philippines to Darwin where American forces are regrouping. Lt. Nick Holden (Tony Curtis) is a reassigned Admiral's Aide with no sea experience who proves unexpectedly useful as the new [[TheScrounger 'Supply Officer']] getting Sherman the parts he needs by humorously unscrupulous means.

Repairs are finally complete and they are ready to get under way, but the No. 1 engine keeps blowing up and sending out black smoke. As the engineers try to fix it, a local witch doctor comes up and starts doing some kind of ritual dance to ward off evil spirits. Sherman tries to get him to leave, when suddenly the engine starts and they are finally able to shove off. Once the sub is headed out to sea, the witch doctor stops dancing and shakes his head, remarking, "They'll never make it."

The ''Sea Tiger'' set sail under strict order to avoid engaging any enemy craft - including lifeboats. Forced to drop anchor at Marinduque for still more repairs Mr. Holden goes ashore and discovers five stranded Army Nurses. A submarine isn't intended to be co-educational but obviously the women cannot be left where they are. Cue sexual tension between a predatory (and engaged) Lt. Holden and Lt. Duran; Captain Sherman and the buxom - and clumsy - Lt. Crandall; and the misogynistic Chief Masters Mate Tostin and Major Heywood.

Sherman intends to unload the nurses at Cebu but the Army Officer in Command refuses to take responsibility for them as he is expecting to be overrun and engage in guerilla operations, possibly for years. Nor can he help Sherman obtain the parts he needs as ''everything'' has been taken up into the hills. Lt. Holden comes up with a solution; he establishes a 'casino' up in the hills which accepts machine parts in exchange for chips leading Sherman to write that Mr. Holden is the only man he knows who will be awarded the Navy Cross at his courtmartial.

One of the items Holden obtains is lead paint for the submarine's undercoat. Unfortunately they have to mix red and white lead resulting in a bright ''pink'' submarine. They have regulation gray paint to go over it but predictably are forced to make a quick departure under fire before this can be done. They also have a dozen or so more passengers, the wives and children of the dealers at Mr. Holden's casino and a goat to provide milk for the children. Even better two of the women are in the last stages of pregnancy.

Sherman naturally assumes that things can't possibly get worse - then they do. Tokyo Rose mocks the bright pink submarine cruising the Celebes Sea and U.S. Naval Intelligence assumes it's deliberate disinformation leading to orders to fire on the ''Sea Tiger'' when she attempts to make contact with a destroyer group. Sherman is forced to resort to most unconventional means to prove that he is 'friend' not 'foe'.

The flashback ends with a color photo of the pink ''Sea Tiger'' steaming into Darwin Harbor. Smiling Admiral Sherman closes the log book and goes on deck to encounter ''Commander'' Nick Holden, now captain of the ''Sea Tiger'' who has just said good-bye to his wife, the former Lt. Duran, and their two sons. A few moments later the Admiral's wife, the former Lt. Crandall, arrives with their four lovely daughters rear ending his staff car and sending it into a bus which then pulls out dragging the Admiral's car behind it by the locked fenders.

He assures her it won't go far, then turn to watch as ''Sea Tiger'' shoves off for the last time, punctuated by an explosion from the No. 1 engine. Sherman shakes his head, remarking, "I guess we never did get that fixed."

!!Tropes featured :

* ArmedFarces
* BavarianFireDrill: Used by Holden during one of his "supply runs". While two others from the ''Sea Tiger'' are finding the parts they need in a military warehouse, Holden is outside. As Holden (who is wearing black clothes and dark face paint) is keeping watch, one guy from the local security patrol approaches him and asks what he's doing there. Immediately, Holden berates him for breaking blackout regulations by not having proper camouflage and goes on to explain that the regs require all personnel to wear black face paint at nighttime or else enemy planes will use the white of their faces to aim bombs at the base. He even offers up his own paint to the guy, who returns to his jeep and shares the paint with his buddy.
* BelligerentSexualTension: Most notably between Tostin and Heywood.
* BrickJoke: As they are trying to get under way, the engine keeps making sounds like explosions accompanied by thick, black smoke. The problem does not occur again while they are at sea (or at least, the smoke doesn't. The engine can be frequently heard gurgling throughout the movie while running on the surface). At the end, as ''Sea Tiger'' is getting under way, there is a sudden sound like an explosion and black smoke, causing Sherman to remark that they never did get that engine fixed.
* TheCaptain: The bemused and put upon Matt Sherman.
* TheCasanova: Lt. Holden.
* DealWithTheDevil: Sherman describes it this way when he orders Holden to get the parts he needs to get ''Sea Tiger'' moving before the Japanese overrun the port.
* TheDeterminator: Sherman will stop at nothing to get ''Sea Tiger'' back out to sea, including allowing Holden to clean out the Admiral's office.

* TheEeyore: Seaman Broom; 'You can't win, my friend...'
* EmbarrassingTattoo: Poor Seaman Hunkle, he's got a female nude tattoed on his chest and feels he can ''never'' go home and marry his fiancee.
* EpicFail: The ''Sea Tiger'' sights a Japanese tanker and is trying to lay in a torpedo strike. One of the nurses mis-steps, accidentally causing the launch button to be hit, and the torpedo not only misses the tanker, but somehow manages to cruise straight up the beach to blow up a truck.
* FriendOrFoe: They are mistaken for a Japanese sub by an American destroyer, which attempts to depth charge them. They end up proving that they are not Japanese by launching the nurses' undergarments from the torpedo tubes.
* HelloNurse: Lt. Crandall, very much so.
* LadykillerInLove: Lt. Holden becomes this after meeting Lt. Duran. Unfortunately he's engaged...
* NotSoAboveItAll: When Holden decides to steal a pig. Sherman has been pretty harsh with Holden up to this point, even though he has been letting his creative scrounging slide for a good part of the movie. So when the guys snag a pig from a local farmer on Cebu, you would expect Sherman to give it back, right? Wrong. One look at the pig (which Holden had hidden in the ship's head) changes Sherman from irate commanding officer to top negotiator, "volunteering" a number of Holden's possessions in compensation for the farmer's lost pig while not really admitting that the pig is on the ''Sea Tiger''.
* PoorCommunicationKills: ''Sea Tiger'' is nearly sunk by their own navy because they think the bright pink sub couldn't possibly be one of their own.
* RecycledTheSeries: almost 20 years later, with Tony Curtis's daughter JamieLeeCurtis as one of the nurses.
* RunningGag: In exterior shots of the ''Sea Tiger'', the engine is occasionally heard belching.
** Holden calling for Ramone whenever he needs something.
* TheScrounger: Lt. Holden
* SubStory
* TokyoRose: A propagandist broadcasting on the radio declares that while the Japanese can't figure out why the Americans would paint a submarine pink, they will not hesitate to sink it on sight.
* WitchDoctor: Lt. Holden hires one of these to see the ''Sea Tiger'' off, on the theory they need all the help they can get. Though even he comments afterward "They'll never make it."
