The official trailer for writer/director Bryan McGuire’s Night Swim has arrived, based on the 2014 short film by McGuire and Rod Blackhurst, and boasts a killer cast to turn their inspired short into a proper horror feature. Wyatt Russell (The Falcon and the Winter Soldier, Black Mirror) stars as Ray Waller, a former major league baseball player whose degenerative illness has forced him into an early retirement. Yet that doesn’t keep Ray from dreaming of a way back to the big leagues. So, Ray, his wife Eve (the always welcome and recent Oscar-nominee Kerry Condon, The Banshees of Inisherin), their teenage daughter Izzy (Amélie Hoeferle, The Hunger Games: The Ballad of Songbirds and Snakes), and young son Elliot (Gavin Warren, Fear the Walking Dead) move into a new home. The home has a beautiful pool. What could possibly go wrong?

What Ray hopes will happen is that the pool in the backyard, so inviting, so glorious, will help him in his physical therapy and get him back out onto the field. To his defense, the pool does look pretty inviting. Unfortunately for Ray and the family, the pool is actually the liquid locus of some seriously sinister forces, the portal from which the home’s horrific pass passes through.

Night Swim boasts not only the aforementioned cast and the imprimatur of Blumhouse but also horror master James Wan as a producer. The first trailer offers a little taste of the madness to come. Swim at your own risk.
