Film: Shock Waves (1977) – Nazi Zombies, Sunburn, and the Art of the Soggy Slog

Somewhere between Gilligan’s Island and Schindler’s List, there’s Shock Waves—a waterlogged fever dream of Nazi zombies in the Florida Keys, shot with the finesse of a tourist’s home movie and the budget of a beer run. It’s a film that answers the question nobody asked: What if the Third Reich rose from the sea, but had really bad Wi-Fi and a swimming pool fetish? You won’t find explosions or exorcisms here—just Peter Cushing muttering through a haze of heatstroke, a boat full of passive-aggressive tourists, and a slow, soggy march toward psychological erosion. It’s not good, it’s not bad—it’s aggressively adequate. Which is why I award it three very wet stars.

The movie’s genesis is a lesson in how desperation, heat, and half-baked historical mysticism can congeal into celluloid. Director Ken Wiederhorn and producer Reuben Trane were hot off winning a student Oscar for a Columbia short film, which is usually where you get poached by Coppola or start directing Hallmark movies. Instead, they were handed a check by investors who wanted just one thing: horror. Not character development. Not nuance. Just horror. So Wiederhorn did what any ambitious young filmmaker would do—he got his hands on The Morning of the Magicians, decided Nazis + magic = box office gold, and flew to Florida with a film crew and a prayer. Thus, Shock Waves was born: a horror film without gore, a thriller without speed, and a zombie movie where the scariest thing is sun exposure.

Filmed on 16mm and later inflated to 35mm like a bloated corpse, the production trudged through 35 days of swampy Florida shooting in places like Crandon Park and two eerily abandoned Biltmore Hotels, both of which now probably have Yelp reviews. The abandoned hotel cost a mere $250 to rent, which might explain why it came with a resident ghost and a leftover 1957 Art Frahm pin-up calendar. Budget constraints were such that the zombies’ now-iconic goggles weren’t even scripted—an extra showed up wearing post-glaucoma eyewear and Wiederhorn thought, “Hell, make it fashion.”

Casting is where the film stumbles into cult royalty. Peter Cushing, horror legend and gentleman of the highest, most Victorian order, showed up for five days, banked $25,000, flew first class, and still managed to look like he’d been tricked into a timeshare presentation. Brooke Adams—pre-Body Snatchers, post-modesty—was meant to go topless but appealed to the wardrobe lady (aka the director’s wife), resulting in the most clothes you’ll ever see in a horror swimming scene. Meanwhile, poor John Carradine wandered around shirtless and squinting at the ocean like he’d lost a bet, earning a cool $5K and zero sunscreen. Fun fact: he did his own underwater stunts. Less fun fact: the man was in his seventies.

The plot—such as it is—follows a boatload of personality-deficient tourists who crash near the rotting Nazi freighter SS Sapona (a real shipwreck, now repurposed for slow pan shots and moist dread). They land on an island, find a dilapidated hotel, and meet Cushing’s Nazi-in-exile, who delivers exposition like he’s reading IKEA instructions. The zombies emerge slowly from the surf like existential regret in uniform, and kill off the cast one by one, mostly through awkward dunkings and staring contests. The only survivor is Brooke Adams, who floats away on a glass-bottom boat, presumably to a therapist.

Critics at the time didn’t so much pan the film as forget it existed. The Monthly Film Bulletin noted the repetitive staging and swamp slogging. Others simply shrugged and wandered back to their Romero box sets. But as years passed and the negative was lost (mysteriously, like the point of the second act), Shock Waves mutated into that rarest of creatures: the cult film. Not because it’s a masterpiece—it’s clearly not—but because it commits to its absurd premise with the dedication of a high school drama club. Roger Waters sampled its dialogue. German TV dressed it up and mocked it as part of the “SchleFaZ” (the worst films ever) series. And horror nerds still argue over which Biltmore scenes were shot where, like monks debating holy relics.

Today, it occupies that hallowed ground in horror history: a noble failure, a soggy oddity, a reminder that sometimes the best bad ideas are the ones that just barely work. Its zombies don’t eat flesh—they just vibe in wet uniforms. Its terror is slow, its tension passive-aggressive, and its finale a long, tragic paddle into madness. But it’s weird. It’s committed. And it’s got Peter Cushing, wearing one glove, lecturing ghosts.

So here’s to Shock Waves: the zombie flick that forgot to run, forgot to scream, and somehow still didn’t sink.

⭐️⭐️⭐️ (3/5)
