Watch On

Genre: Sci-fi thrillerRuntime: 2h 22mWhat it's about: Steven Spielberg returns to the genre he helped define with an alien conspiracy thriller. Emily Blunt stars as Margaret Fairchild, a TV meteorologist who suddenly speaks an alien language during a live broadcast. She's forced on the run with cybersecurity analyst Daniel Kellner (Josh O'Connor), who has stolen classified evidence of extraterrestrial life. As the government closes in, the pair race to expose a decades-long cover-up.Why it's worth your time: No, it's not "Close Encounters of the Third Kind" 2.0, and that's fine. Even a mid-tier Spielberg sci-fi movie is eminently entertaining, elevated by Emily Blunt's terrific performance, some jaw-dropping set pieces and John Williams' soaring score.Where to stream: Prime Video (with purchase)2.
