Day The Earth Stood Still, The (2008)

A remake of the 1951 sci-fi classic of the same name, THE DAY THE EARTH STOOD STILL follows astrobiologist Helen Benson (Jennifer Connelly) as she is unceremoniously plucked from her everyday life with her stepson (Jaden Smith), and whisked away to consult the government on a top-secret matter. That matter happens to be the arrival of a massive glowing sphere in Central Park, accompanied by a towering robot-like protector dubbed Gort and an alien ambassador named Klaatu (Keanu Reeves), who takes up human form to communicate with the people of Earth. When Klaatu finds himself faced with hawkish, uncompromising officials, he goes on the run with Benson and her son as the fate of the world gradually becomes clear.
