The Coen Brothers' new film Burn after Reading has claimed the top spot in the UK and Ireland box office chart after its first weekend on release.
The comedy took £2.04 million in its first three days in cinemas to unseat last week's number one film The House Bunny.
The latter, starring Anna Faris, fell to fourth as new releases Eagle Eye and Igor reached the top three.
Burn After Reading, the highest of this week's new entries, sees George Clooney, Brad Pitt and John Malkovich in a comic tale of CIA intrigue, while Eagle Eye features Shia LaBeouf and Michelle Monaghan being manipulated by mysterious unseen forces in a new thriller from Disturbia director DJ Caruso.
And the likes of John Cusack, Eddie Izzard and Steve Buscemi provide the voices for animated hit Igor, the story of an evil scientist's assistant's dreams of making his own scientific discovery.
Mamma Mia! retained its place in the top ten after 15 weeks on release while The Rocker just missed out after its opening weekend, debuting in 11th.
