Alien Klaatu arrives on Earth to warn of an impending global apocalypse
Sci-fi movie The Day the Earth Stood Still has topped the North American box office in its opening weekend, according to early studio estimates.
The remake of the iconic 1951 film, which was largely panned by critics, stars Keanu Reeves as an alien who comes to Earth. It took $31m (£20.6m).
Festive comedy Four Christmases slipped to second place with $13.3m (£8.8m).
Vampire drama Twilight fell to three with $8m (£5.3m) taking its total haul to $150m (£99.7m) over four weeks.
"Audiences are moving to see The Day the Earth Stood Still - it's a visually stunning movie with timely issues everybody on this planet can relate to," said Fox distribution executive Chris Aronson.
