This is the film that started the Nazi zombie craze (most recently seen in DEAD SNOW - 2008) and it's still one of the best. The fact that this film manages to be creepy without relying on gross-out gore, but rather with mood and atmosphere, is all the more remarkable. Even more amazing is that it was directed and co-written by Ken Weiderhorn, who would later give us such inferior films as the frat house scatfest KING FRAT (1979), the B-level slasher film EYES OF A STRANGER (1981), the fractured mess of a horror film DARK TOWER (1987) and the mostly unfunny horror sequel RETURN OF THE LIVING DEAD PART II (1988), so it seems he shot his creative wad on his freshman effort. In the film's beginning, it is explained that during World War II, the Nazi SS High Command began top secret experiments in the supernatural (it is now a well-known fact that Hitler had deep interests in the occult) to turn soldiers into indestructible zombie storm troopers, which was code-named "The Death Corps." (the shooting title of the film). Unfortunately for Germany, the war ended before The Death Corps. could be put into action outside Germany and a platoon of the Nazi zombies have been waiting in a sunken freighter off the coast of Florida to be reactivated. It is now 1976 and a fishing boat spots a glass-bottomed dingy drifting aimlessly in the Florida seas. On the dingy is a dehydrated Rose (Brooke Adams; THE DEAD ZONE - 1983) and the story she has to tell is the basis for the rest of the film. We flashback to a few weeks earlier, where Rose and three other passengers are on a small tour boat trolling around the islands. The temperamental boat's even more temperamental Captain Ben (John Carradine; FRANKENSTEIN ISLAND - 1981) complains to first mate Keith (Luke Halpin; MR. NO LEGS - 1979) that the boat must have "accurate navigation" ("It's a sailor's best friend!"), but the sun starts to look strange (the whole sky turns orange) and they lose compass bearings and radio contact. This visibly unnerves Captain Ben and his crew (The boat's cook, Dobbs [Don Stout], says, "The sea spits up what it can't keep down" which is very prophetic), but they try to hide it from the passengers, which besides Rose, includes an always-complaining Norman (Jack Davidson), his much put-upon wife Beverly (D.J. Sidney) and the physically-fit Chuck (Fred Buch). In the middle of the night, the boat is sideswiped by a ghost freighter, which seemingly rose out of the ocean depths and has gotten itself stuck on a sandbar. The next morning, everyone discovers that they are stuck on the same sandbar next to a mysterious island, but Captain Ben is missing. When it is deemed that the boat is no longer seaworthy, everyone takes the glass-bottomed dingy to the island, where they discover Captain Ben's dead body underwater. On the island is a decaying old seaside hotel and they use it for shelter, but it's plain to see someone already lives there (a working fish tank and a Gramophone playing an old 78 rpm record are just two clues). That occupant is an old SS Commander (Peter Cushing; his next film was STAR WARS!), who has been hiding on the island since the end of WWII, and he is just as surprised as everyone else to see the rusted freighter on the horizon. This can only mean one thing: The Death Corps. Have been reactivated and they are ready to kill. The blonde-haired, goggle-wearing, jackbooted zombies rise out of the ocean (a very well-done and eerie sequence) and begin killing the stranded castaways, beginning with Dobbs, who Rose finds while taking a swim in the lagoon (his body is bloated and misshapen). The SS Commander explains to the group what they are up against and offers them a small sailboat to make their escape, but as we already know, there will only be one survivor of this ordeal. While there is very little plot to this low-budget horror flick (Weiderhorn co-wrote the screenplay with John Harrison [MURDER BY PHONE - a.k.a. BELLS - 1982]), SHOCK WAVES still manages to be a scary, moody film thanks to some totally creepy underwater sequences (the zombies walking on the sea bottom is a unique sight and Underwater Photographer Irving Pare captures it perfectly) and the look of the zombies themselves (Makeup Design by Alan Ormsby; CHILDREN SHOULDN'T PLAY WITH DEAD THINGS - 1972), outfitted in SS uniforms and looking like the Master Race with a really bad case of acne. I also like that these zombies aren't flesh eaters. They're fast-moving undead whose only job is to kill, even killing the SS Commander who created them (Peter Cushing looks impossibly thin and frail here). There's very little blood or gore on view (just shots of dead bodies and zombies rotting when their goggles are pulled off), but there is no real call for it here, because this film relies more on atmosphere than blood and guts. Must viewing for fans of Val Lewton-esque horror. This had various VHS releases, from Prism Entertainment, American Video and Starmaker Entertainment, but the only way to really watch this film is the widescreen DVD from Blue Underground, mastered from the director's own vault print. It blows all the VHS editions out of the water. Rated PG. { text from critcononline.com }
