Available to own on DVD and Blu–ray Monday 20th April, 2009! Renowned scientist Dr. Helen Benson ( Jennifer Connelly ) finds herself face to face with an alien called Klaatu ( Keanu Reeves ), who travels across the universe to warn of an impending global crisis. When forces beyond Helen‘s control treat the extraterrestrial as a hostile and deny his request to address the world‘s leaders, she and her estranged stepson Jacob ( Jaden Smith ) quickly discover the deadly ramifications of Klaatu‘s claim that he is "a friend to the Earth." Now Helen must find a way to convince the entity who was sent to destroy us that mankind is worth saving – but it may be too late.
