Blumhouse has a new horror movie out, leaving questions about if Night Swim has a post-credits scene teasing more about the story. The 2024 horror movie is based on a short film by director Bryce McGuire made a decade ago that focuses on a family discovering the truth about their supernaturally haunted pool. Night Swim stars Kerry Condon and Wyatt Russell as the mom and dad of the Waller family. After they move into a new house, horror begins to encompass the family's life due to the threat posed by what exists within their pool.
