This movie looks genuinely stupid.
No, a person can’t be swallowed by a sperm whale (strike #1) and no, a person is not going to survive for an hour in the whale’s guts (strike #2). A very large sperm whale is the only whale with a gullet wide enough to swallow an object the size of a person, but not one wearing all the gear involved in scuba diving, and especially not since the whale is adapted to consume soft squishy prey. Furthermore, the gut isn’t just a passive volume — the victim is going to be mashed and squished by the muscular walls.
ScienceNews tries to break the news gently.
But no one has ever observed this process in sperm whales. And researchers aren’t sure sperm whales actually swallow prey whole. When these elusive giants do surface with squid, it’s either with “literal chunks hanging out of their mouths or chunks floating behind them,” Gero says.
Swallowing people is also not in sperm whales’ nature, Reidenberg says. It makes for a thrilling movie night, but “these whales are very gentle when they’re around people who are not bothering them.” So while physiologically possible, their behavior and taste for deep-sea creatures make the events “very, very unlikely.”
You’re also not likely to get hoovered up by a sperm whale by accident. These whales can dive more than two kilometers deep in search of a meal — far deeper than human divers can reach, Gero says.
Popular Science consulted the same whale biologist

“More than likely, the human drowns the second they get smashed into the mouth of the whale, whether they were drawn in by a squid or accidentally brought into the mouth of a whale,” he says. “My guess is the person dies the second they enter the mouth.”
Gero raises another interesting possibility. Sperm whales usually prey on boneless squid, so consuming a scuba-outfitted human could be a choking hazard, and could choke to death.
This would certainly make for a shorter movie, but Gero notes that the whale’s body could also have a more lively response to an unwanted foreign object in its mouth.
“When I swallow something that I shouldn’t have, it’s like a non-controllable response — your body just starts moving its mouth and coughing,” Gero says. “In that sort of movement, or freakout, it probably is going to do a lot of physical damage to the human.”
Although Gero acknowledges that he is not a whale anatomist, he still believes that it would be highly unlikely for any living creature to make it into the stomach of a sperm whale, let alone set up camp there.
“There are acids and gases,” he says. “The digestive tract of any mammal is not meant to be a livable place for any prey that ends up there.”
So, yeah, it’s a ridiculous movie with a bad premise.
But you know who is thrilled by it? Ken Ham.
Could Jonah have survived three days and three nights inside the belly of a great fish?
Well, I think more people will be asking that question next month after a new survival thriller movie, Whalefall, hits the box office. This movie is based off a 2023 novel of the same name by author Daniel Kraus, and the premise is basically this: A young man diving in the Pacific Ocean is accidentally swallowed by a hunting sperm whale. He only has one hour’s worth of oxygen left and must find a way to escape the belly of the beast.
Of course, such a story immediately reminds viewers of the biblical account of Jonah—and the author apparently intended that. In an interview he said,
The impetus for the book was that I wanted to treat the Biblical Jonah story with scientific and biological accuracy. I talked with whale experts as I developed the plot, and they would listen to my ideas and say, “You know, that is theoretically possible.” So, that’s why it’s believable: We got the science right.
No, he didn’t get the science right. He talked to experts and cherry-picked the most charitable, tentative statements they made, and scurried off to write a stupid story that would sell, being especially attractive to brain-dead Christians, like Ken Ham. And now we’re going to have to deal with apologists who will claim it’s possible because they saw it in a movie.
Ham did say one honest, revealing thing.
Just as there is no fully naturalistic explanation for how Jonah could have survived such an ordeal, there’s no naturalistic explanation for how Jesus could be crucified, die, be buried in a tomb, and then three days later walk out of that tomb alive. It was a miraculous event that was only possible because God is omnipotent and nothing is impossible for Him.
The story makes no sense, there is no naturalistic explanation, but he’s going to believe it because god said so, and it was a miracle. Who needs a reasonable, factual explanation when you’ve got the whims of a god to back you up?
