Almost 50 years ago, Steven Spielberg directed “Close Encounters of the Third Kind,” the story of an average man who discovers that humanity may not be alone in the universe. Over the decades, Spielberg has directed several movies about what would happen if humanity made contact with aliens. Would the aliens be kind like the title character in “E.T. the Extra Terrestrial”? Would they be cruel like the murderous aliens of “War of the Worlds”? And regardless of what the aliens were like, would we humans be ready to receive them?

Spielberg returns to the question of whether we’re alone in the universe, and what it might mean if we’re not, with his new film “Disclosure Day.” Today, he sits down with Rachel Abrams, a host of “The Daily,” to talk about the film, and about what he has learned over five decades of making movies about aliens.
