The Black Phone is a 2021 American supernatural horror film directed by Scott Derrickson from a screenplay coauthored with longtime collaborator C. Robert Cargill. It stars Mason Thames as Finney, a teenage boy abducted by a serial child killer known colloquially as The Grabber. When Finney encounters a mystical black rotary phone in captivity, he uses it to plot his escape by communicating with the ghosts of The Grabber's slain victims. Madeleine McGraw, Jeremy Davies, and James Ransone also feature in the principal cast. Derrickson and Cargill produced The Black Phone in association with Blumhouse Productions CEO Jason Blum. Universal Pictures oversaw the film's commercial distribution, and funding was sourced through a Universal–Blumhouse co-production pact and tax subsidies from the North Carolina state government.
