Disney Animation Studios bosses have a new record breaker - Wreck-It Ralph has landed the company's highest-grossing opening weekend for an animated movie.

The film about a destructive video game character, starring John C. Reilly, has grossed $49.1 million (£30.7 million) in America - almost twice as much as Denzel Washington's latest release Flight, in which the Oscar winner plays an alcoholic pilot.

Ben Affleck's Iranian hostage crisis drama Argo falls to third with a $10.2 million (£6.4 million) weekend take.
