''Shock Waves'' is a 1977 horror film. Its cast features Creator/PeterCushing and Creator/JohnCarradine.

During World War II, ThoseWackyNazis created [[NaziZombies the Death Corps]], nigh-invincible troopers made from the dead German soldiers. After carrying out few missions, they disappeared into the sea at the end of the war.

An undersea quake years later awakens them from their rest, and they go after shipwrecked holiday-goers who are stranded on an island nearby.

!!These tropes rose up from the depths:
* AbandonedArea: The once elegant hotel where the SS officer has been holed up for years.
* AssholeVictim: The extremely whiny Norman.
* ClosedCircle: The island.
* DeathByCameo: Creator/JohnCarradine as Captain Norris isn't in the movie long before getting KilledOffscreen somehow.
* FinalGirl: Rose.
* FlareGun: After colliding with the suddenly ascended ship, the yacht captain fires his flare gun to reveal its position. It's also [[ChekhovsGun Chekhov's Flare Gun]].
* FreakOut: It is, after all, a horror movie. [[spoiler:Some characters, like Keith, have phobias that don't show up until catastrophic freak outs.]]
* ForegoneConclusion: Rose being the only survivor.
* GhostShip: Lampshaded by the captain.
* GoodScarsEvilScars: The SS officer has a scar going over his right eye.
* GoneHorriblyRight: The Death Corps project.
* TheHermit: The former SS officer, who has lived on his own since the war.
* HowWeGotHere: The film opens with Rose being rescued from the sea, who then tells us the events leading to it.
* ImplacableMan: The zombies never have different facial expressions and indifferently wade through anything and everything to get to their victims.
* KilledOffScreen: Captain Norris. It's implied (but never confirmed) that he got killed by a zombie while attempting to repair the ''Bonaventure'''s engine.
* NaziZombies: The entire plot.
* NoNameGiven: The elderly SS officer played by Creator/PeterCushing.
* OurZombiesAreDifferent: They are undead soldiers who are driven by their need to kill.
* PeekabooCorpse:
** Rose goes on a swim in the lake, only to run into Dobbs' corpse.
** Norris' (the captain) corpse is also discovered this way. As the castaways are rowing ashore, Norman's wife is startled by Norris floating face up underneath them through the boat's glass bottom.
* SpitefulSpit: The SS commander when Keith keeps following him and asking questions.
* StupidJetpackHitler: [[NaziZombies Nazi soldiers resurrected]] by science to fight for the Third Reich under the sea!
* TemporaryBlindness: [[spoiler:Or at least it might've been temporary, but for other events.]]
* WeakenedByTheLight: That's why the Death Corps wear goggles.
* ZombieGait: The Death Corps exhibit a stiff walking style. It's a little different from the shambling, uncoordinated stagger of most zombies; since they're (kind of) intelligent, they merely walk stiffly but purposefully toward a goal.
