Sci-fi movie Gravity has entered the UK and Ireland box office chart at number one after taking £6.2 million in its first four days in cinemas.
The 3D film, about astronauts adrift in space, displaced last week's top film, superhero sequel Thor: The Dark World.
Philomena, starring Dame Judi Dench and Steve Coogan, maintained its box office momentum at three, taking £1.2m with only a 7% drop-off in takings.
Gravity was the only new release to make its debut in this week's Top 15.
The film is directed by Alfonso Cuaron, whose other credits include Harry Potter and the Prisoner of Azkaban and the dystopian thriller Children of Men.
According to its distributor Warner Bros, nearly 90% of ticket sales were for 3D screenings, setting a new benchmark for the format in 2013.
Gravity was released in the US and Canada last month and made $55.5m (£34.6m) in its opening weekend - the biggest October debut on record.
