'Night Swim' trailer turns Marco Polo into swimming pool horror

A new trailer for Night Swim has arrived, putting a horror spin on the classic swimming pool game Marco Polo.

Produced by M3GAN's James Wan and Jason Blum, Night Swim follows a family of four who move in to a new home with an old swimming pool. Some work needs to be done to get the swimming pool in working order, as it hadn't been used in 15 years, but soon the Waller family is ready to host summer parties.

Or they would be, if there wasn't something sinister and supernatural lurking in its depths.

Night Swim arrives in theatres Jan. 5.
