Famed US director Steven Spielberg offered a sneak peek of his upcoming film "Disclosure Day" Wednesday, his latest movie about aliens and humanity since he first tapped into the genre 50 years ago.

Spielberg presented the film at CinemaCon in Las Vegas, the annual conference where movie studios present upcoming releases to movie theater owners.

The film shows humanity crossing paths with extraterrestrial life, a plot reminiscent of his 1977 film "Close Encounters of the Third Kind."
