Based on a short story by Joe Hill (son of Stephen King), the 2021 horror flick “The Black Phone” relied more on suspense and jump scares than it did on gore and OTT special FX. The movie’s supernatural element was that the dead adolescent male victims of The Grabber (a masked Ethan Hawke) communicated with Finney (Mason Thames), the serial killer’s latest captive, via a non-functioning black telephone.
