The MCU’s Karen Gillan (Nebula from Guardians of the Galaxy and Avengers: Endgame) stars in a double role as a woman and her clone in the caustic indie science fiction movie Duel. Riley Stearns, writer-director of The Art of Self-Defense and Faults, uses an unlikely cloning scenario to consider self-destructive and self-reconstructive violence. In theaters April 15, in digital and streaming release May 20.
