Directed by Meet the Parents writer John Hamburg, the film knocked Rings sequel The Return of the King off the top of the US box office in January.

It stars Aniston as a free-spirited waitress who strikes up a romance with a neurotic risk assessment analyst.

The only other top 10 entry was the Ron Howard drama The Missing at number six.

Last week's number one, The Haunted Mansion starring Eddie Murphy, slipped to second place.
