American Hustle tops the first UK box office top 10 of 2014, ahead of The Hobbit: The Desolation of Smaug and Disney animation Frozen.
Peter Jackson's second Hobbit movie had been enjoying a Smaug-like reign atop the box office mountain, but David O Russell's drama had enough star power and awards season hype to dethrone Warner Bros' fantasy adventure.
Receiving a wide release after a limited run late last month, American Hustle took £3.46 million compared to The Hobbit's £3.2m and Frozen's £2.92m.
New entry's Last Vegas - starring Michael Douglas, Morgan Freeman and Robert DeNiro - and horror film Paranormal Activity: The Marked Ones complete the top five.
Elsewhere Mandela: Long Walk to Freedom opened at seven, bringing in £1.47 million.
