MAMMA Mia has become the biggest grossing British film of all time at the UK box office. The film has made 66,995,224 in the UK, beating Harry Potter and the Sorcerer's Stone. Casino Royale moves down a place to number three with the top 10 completed by other Harry films, The Full Monty, Bridget Jones' Diary and Love Actually. Titanic is the only film to have made more in Britain at 69 million. Worldwide, the film is already one of the most profitable movies ever, recently crossing the $500m box office mark. The film, based on the 1975 ABBA hit song and the musical stage play, stars Meryl Streep, Colin Firth and Pierce Brosnan. Universal Pictures International president David Kosse told The Hollywood Reporter: "Since its release in July we've seen people around the world coming back to see the film again and again." Last month it was reported that the financial crisis had resulted in the best summer cinema attendance in almost 40 years. Mamma Mia was widely credited with helping make it the best for British cinema admissions since 1972.   " Telegraph
