Night Swim is Blumhouse's first horror film of 2024 and fans went in not sure what to expect. The Night Swim trailer didn't reveal much about the film, which only made people that much more interested. From the brief image of a teen being terrorized by an unseen force inside a pool, most people assumed Night Swim would be about a haunted pool, but that was all they had to go on. Night Swim also didn't have a large budget. In total, the film spent about $15 million on the production. While that might sound like a lot, for a movie, it's chump change.
