Josh O’Connor Joins the Cast of Steven Spielberg’s Mysterious UFO Movie

Steven Spielberg is reteaming with screenwriter David Koepp (Jurassic Park) on an untitled UFO movie, with Universal recently dating the film for theatrical release on May 15, 2026.

Emily Blunt (A Quiet Place, Edge of Tomorrow) has signed on to star in the untitled event movie, and Deadline reports today that Josh O’Connor (Challengers) has also joined the cast.

Colin Firth, Colman Domingo and Eve Hewson will also star in the untitled movie from Amblin and Universal. No plot details have been revealed at this time. Stay tuned.

Steven Spielberg is of course no stranger to extraterrestrial encounters, directing two of the greatest alien movies of all time: Close Encounters of the Third Kind in 1977 and E.T. in 1982. It’s an arena he returned to in 2005, directing an adaptation of H.G. Wells’ War of the Worlds.

Even more recently, Spielberg’s Amblin Entertainment produced the Netflix docuseries “Encounters” last year, which explores true stories of human contact with otherworldly phenomena. You can stream all four episodes of “Encounters” over on Netflix right now.
