Starring Sandra Bullock and (for half the film) George Clooney, there was no stopping Gravity this week.
Gravity was released at the UK box office in November last year, debuting at the top of the Box Office, where it spent 2 weeks.
After 16 weeks the film is still in cinemas as may well stay for a few more weeks after it's success at the Oscars.
Last weeks top film, Thor The Dark World, falls down to 2 this week.
