Companion opens on what appears to be a perfectly ordinary romantic getaway — Iris and Josh have arrived at a lakeside retreat with two other couples, the kind of weekend that movies use as shorthand for comfortable modern life. Within minutes, something is wrong in ways the film refuses to name directly, and by the time it does name them, everything you thought you understood about the power dynamics in the opening scene has inverted completely. Drew Hancock's debut feature is the kind of thriller that requires total viewer participation from the first frame.

Sophie Thatcher plays Iris with calibrated uncertainty — she conveys something between contentment and suppressed something else that the film slowly reveals to be the most precisely accurate emotion available to her. Jack Quaid is unsettling as Josh in ways that only register gradually, and the supporting cast (Harvey Guillén, Lukas Gage, Megan Suri) each carries their own secrets that amplify the story's central revelation rather than distract from it. Hancock's screenplay is meticulous about planting information the audience will retroactively recognize as obvious once the film declares its hand.

Companion was released by Warner Bros. in January 2025 and became one of the year's most discussed genre films — a word-of-mouth phenomenon driven by audiences who insisted on telling people to see it without revealing what they were about to experience. The film earned praise for its wit, its central performance, and its willingness to use a genre premise as the vehicle for something more interesting than genre alone provides. It streams on Max, and is best experienced knowing as little as possible before pressing play.
