A 1965 WorldWarII epic starring JohnWayne and KirkDouglas, and both the last WorldWarII film and John Wayne film to be made in Black and White.
For the trope of the same name, go [[Main/InHarmsWay here]].
!!In Harms Way includes examples of the following tropes:
* AnachronismStew: The hairstyles and civilian dress in the movie were contemporary to the time it was made, rather than the time it takes place. Similarly, the plane features various smaller vehicles that were not in the US inventory at the time, including the HU-16 Albatross Flying Boat and the M151 MUTTs pretending to be WWII era jeeps.
* BackedByThePentagon: The film received extensive help from the Navy and Marine Corps, including being allowed to film on Navy ships, though some careful work had to be done to hide the more modern equipment on the ships (there were no missile cruisers or destroyers in 1942).
* BadassFamily: Rock and his son Jeremiah are both naval officers, and end up fighting in the same naval battle.
* DavidVsGoliath: The film's climax, with Rock Torrey leading an outmatched force of cruisers, destroyers, and PT boats against a much larger Japanese force.
* DeathBySex: Seemingly the cause for DoomMagnet.
* DeathEqualsRedemption: After he [[MoralEventHorizon rapes Annalee]], [[spoiler: Paul Eddington]] goes on a OneWayTrip in a bomber to try and find the Japanese fleet, and is shot down and killed shortly after calling his sighting in.
* DoomMagnet: [[spoiler: Paul Eddington]]. Every character within two degrees of separation of him ([[DeathBySex via sexual relationships]]) dies before the credits roll.
* DrivenToSuicide: Both [[spoiler: Eddington and Annalee]].
* LeeroyJenkins: Rock Torrey decides to pursue the Japanese forces that launched the attack on Pearl Harbor, only for his ship to be torpedoed by a Japanese submarine he blunders across.
* MilitaryBrat: Jeremiah Torrey, who has become an officer in the Navy like his father. The two have a strained relationship.
* OperationBlank: "Skyhook", a planned offensive to sieze the island of Levu-Vana to use as a base for American heavy bombers.
* ReassignedToAntarctica: Eddington, after his wife's cheating ways, and her death during the Pearl Harbor raid (along with an extramarital lover of hers) drives him to drinking and [[BarBrawl brawling]]. He ends up as "officer in charge of piers and warehouses" on part of Honolulu.
* [[AirstrikeImpossible Seastrike Impossible]]: Jeremiah's PT boat squadron makes a torpedo run on the [[DavidVersusGoliath much larger Japanese fleet]] under cover of darkness. They get badly mauled for their trouble, but cripple several Japanese ships. [[spoiler: Jeremiah is killed in the battle.]]
* YourCheatingHeart: Eddington's wife is having a one night stand with an Army aviator while he is out to sea when the film starts on December 6, 1941. The next morning, [[LaserGuidedKarma both of them are killed together during the Japanese air raid.]]
