The Day The Earth Stood Still - (2008) (Blu-ray disc)

A spacecraft lands in Central Park, and an alien emerges, with a menacing robot whose destructive powers defy imagination.

Rebuffed in his efforts to warn the Earth's leaders of it's impending doom, the alien, Klaatu, takes to the streets. Klaatu's plea for peace is embraced by a pretty, young woman and an eminent scientist, but the rest of humanity reacts with mistrust, fear and violence.

With time running out, Klaatu is forced to demonstrate his awesome powers, teaching all of mankind a lesson for the ages.
