As one guest notes, you saw Gwyneth Paltrow’s “Sliding Doors” (1998), it’s somewhat the same paradox.
If that sounds unbearably erudite, writer-director James Ward Byrkit offsets the headiness with drollness, such as a reference to the 1998 Gwyneth Paltrow rom-com Sliding Doors.
His characters even reference a previous film that drew on such watered-down multiverse theories, the rom com Sliding Doors.
However, there's one lone house in the neighbourhood that still has its lights on, and the friends discover that its inhabitants look strangely familiar... Writer/director James Ward Byrkit has basically taken a Twilight Zone episode and stretched it to feature length - the mind-bending plot invokes both Sliding Doors and the Schrödinger's cat paradox as the guests grapple with potential parallel realities.
At one point, when everyone’s trying to figure out what the hell is going on, Laurie brings up Sliding Doors, the Gwyneth Paltrow movie about two alternate realities that diverge based on whether the heroine boards or just misses a train.
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.
