In Shyamalan's movie, the baby dies from starvation after less than a minute, since it's established that children on the beach need large amounts of food to sustain their rapid accumulation of mass. It's here that Old's story diverges from Sandcastle's in a major way. Two of the teens have sex, and the girl goes through an extremely accelerated pregnancy. An elderly woman dies first, followed by a dog, and the children grow up into teenagers. When the young woman's body is found in the water, alarm spreads through the group, which is only further compounded when they realize how quickly they're ageing. Several groups of people arrive at the beach, starting with a mother and father and their young son and daughter. A young woman takes off her clothes on the beach and goes walking into the ocean, watched from the shore by a man (though in the graphic novel the man is Amesan, a Kabyle jeweller from Algeria, not a semi-famous rapper called Mid-Sized Sedan). The plot elements of a mysterious resort and a nefarious manager who tricks people into going to the beach aren't really present in Sandcastle, though the story does begin in roughly the same way. How Old and Sandcastle's Stories Are Different " The graphic novel is almost picture-perfect as a trap for me because it's incredibly visual and Twilight Zone–y and it has an enigmatic ending." Shyamalan was compelled to adapt the graphic novel by a desire to " finish this story, and put it up on screen." Here's how Old's adaptation of Sandcastle is both similar and different to the original story. " I kept it in my bag and kept thinking about it," the filmmaker said. In an interview with Entertainment Weekly, Shyamalan explained that the graphic novel was given to him as a gift by his daughters. In 2017, Shyamalan shared on Twitter that Old was one of the graphic novels he was reading in search of inspiration while writing the screenplay for Glass. With the clock ticking, the people trapped on the beach must find a way to escape before they die of old age. For every half-hour that passes, people on the beach physically age by a year, reducing their lifespans to a single day. Starring Gael García Bernal, Vicky Kriepps and Alex Wolff, Old is set on an idyllic beach that has an insidious and ultimately lethal effect on anyone who spends time there. But while Old and Sandcastle share the same basic premise and a few plot points, Shyamalan's film goes a lot further in explaining the central mystery and also chooses to give its characters a happier ending. Night Shyamalan's new beachside horror Old is based on the graphic novel Sandcastle, by Oscar Lévy and Frederik Peeters. Warning: SPOILERS ahead for Old and Sandcastle.
