The combination of Julia Roberts and La Joconde weren't enough this week to unseat Tom Cruise's The Last Samurai now in its second week at number one.

Mona Lisa Smile opened at number two with a respectable 337,134 admissions on a relatively low 394 screens for a film starring the world's most famous actress.

21 Grams took fourth position with a healthy screen average of $8,416 - unseating Lost In Translation and The Lord Of The Rings which has been working its way down the chart over the past two weeks but which could bounce back thanks to the slew of Oscar nominations the film received last week.

Horror remake The Texas Chainsaw Massacre is the only other new film in the top 20 at number 7.
