LEONARDO DICAPRIO'S new thriller Blood Diamond proved a gem at the box office as it scooped the top spot.

The movie, which stars Dicaprio as a South African mercenary, made £1.18million in the past week.

Just a fraction behind were part-animated fantasy Arthur and the Invisibles and dark drama Notes on a Scandal, while musical Dreamgirls is at number four.

Last week's number one, Rocky Balboa, fell to number five.

Dicaprio has been Oscar nominated for his role in Blood Diamond.
