I watched the new Whalefall trailer with my arms uncrossed, which I want credit for, because by the halfway point I had fully reverted to fetal-position-on-the-couch mode. If you haven't seen it yet, the trailer over at MSN is doing the thing great horror marketing is supposed to do: make you feel the movie in your body before you've bought a ticket.

Quick setup for anyone coming in cold. Whalefall is based on the Daniel Kraus novel about a diver who gets swallowed by a sperm whale and has roughly an hour of oxygen to figure out how to not die inside it. That's the premise. That's the whole premise. There's some father-son emotional baggage woven through the book too, but let's not pretend that's what has people clutching their chests. A man. A whale. A countdown.

The trailer leans all the way into the claustrophobia, and it works. Lots of darkness, lots of wet breathing sounds, lots of shots where the frame itself seems to be squeezing shut around the diver. I've seen my share of tight-space horror this year and this one made my shoulders climb up around my ears, which is the highest compliment I can pay a trailer for this genre.

And I'm not the only one having flashbacks. The comparison floating around since the trailer dropped is Open Water, the 2003 low-budget nightmare about two divers left behind by their tour boat in shark-infested water. Somebody in the comments of every post about this thing has brought it up, and they're right to. Open Water worked because it took the vast openness of the ocean and made it feel like a coffin. Whalefall flips that trick, taking a creature and making it feel like an enclosed room. Same dread, opposite architecture.

The other spiritual cousin here, obviously, is 127 Hours, because the whole swallowed-alive-with-a-ticking-clock structure is basically Danny Boyle's arm-trap movie relocated to a stomach. If the film version can pull off even half of what Boyle did with a guy pinned to a canyon wall, we're in good hands. Kraus, meanwhile, is no stranger to body horror and visceral dread, he co-wrote The Shape of Water novelization-adjacent work and has spent his whole career in the weird end of the pool, so the source material has real teeth. Or, well, baleen. Sperm whales have teeth. You get me.

No firm wide-release details to pass along beyond what's in the reporting, so keep an eye out for dates as we get closer. What I can tell you is the trailer already did its job on me: I went from casual awareness to genuinely needing to see this on the biggest screen possible, ideally from a seat near an exit.

Jess Wingo walked past my desk while I was watching it and asked why I was breathing like that. I told her a whale ate a guy. She kept walking. Anyway, watch the trailer, don't watch it at lunch, and if Open Water scarred you back in 2003, maybe stretch first.
