More than two decades after his last major venture into extraterrestrial storytelling, Steven Spielberg is back with Disclosure Day, a sci-fi thriller that taps into one of the most culturally charged questions of the modern era: what governments know about UFOs, and whether the public will ever be told. The film premiered in theaters on June 12, 2026, starring Emily Blunt, Josh O'Connor, and Colin Firth in a story built around government secrecy, whistleblowing, and the enduring human compulsion to find out what is being hidden.
