A comet passing close to Earth stirs up spooky space-time anomalies in this minimalist sci-fi thriller. Initially, rumors of the celestial object’s possible effects provide fun dinner party banter at the home of married couple Mike (Nicholas Brendon, whose character’s history as a “Roswell” star winks at his “Buffy the Vampire Slayer” alum status) and Lee (Lorene Scafaria).
Guest Em (Emily Foxler), who’s been studying up on the subject, is startled when her iPhone screen randomly shatters. Soon, the lights are out and the one house down the street with its power still on turns out to be, impossibly, their own — with other versions of themselves in it.
Writer/director James Ward Byrkit, in his feature debut, achieves effective chills with only eight actors and a living room, intermixing quantum physics (shout-outs range from Schrödinger’s cat to “Sliding Doors”) with the very mundane human tendency toward bad judgment calls in a crisis.
