Andrea Riseborough is 'Rock' solid

To co-star in film based on Graham Greene's novel

NEW YORK -- Andrea Riseborough is heading to "Brighton Rock."

The British actress will play the female lead opposite Sam Riley in the pic based on the Graham Greene novel. She replaces Carey Mulligan, who had been attached to the role.

"Rock," which marks the directorial debut of "28 Weeks Later" scribe Rowan Joffe, originally came to the screen via Richard Attenborough in 1947. It centers on a small-time gangster who kills a rival and finds his life in turmoil as he faces blackmail threats from a waitress (Riseborough) who knows about the murder.

BBC Films and Optimum Releasing are behind the pic, which aims to shoot this year in the U.K.

Riseborough, signed recently by CAA, had a role in last year's Mike Leigh dramedy "Happy-Go-Lucky." She also appears in "Never Let Me Go," Fox Searchlight's dark drama based on the Kazuo Ishiguro best-seller, in which she will play opposite Mulligan.
