Avatar on top for a fifth week in the U.S.

James Cameron’s sci-fi epic, which claimed six honours at the Critics Choice Movie Awards on Friday night (15Jan10), has now passed Star Wars to become the third biggest-grossing film in America. The movie is already the second most successful movie of all-time globally, behind Cameron’s Titanic.

Avatar grossed another $41.3 million (£25.8 million) at the U.S. box office at the weekend (15-17Jan10) – $10 million (£6.25 million) more than The Book of Eli, which opened in second place.

The Lovely Bones made its wide-release debut and comes in at three on the new countdown, while Alvin and the Chipmunks: The Squeakquel and Sherlock Holmes round out the new top five.
