Vincent Cassel has signed on to star in David Cronenberg's "Eastern Promises" for Focus Features and BBC Films says The Hollywood Reporter.
The London-based thriller centers on a nurse (Naomi Watts) investigating the identity of a young Russian prostitute who dies in childbirth. She unwittingly stumbles into a Russian police operation that seeks to expose a major Russian Mafia prostitution ring.
Cassel has been cast as Petrid, whose family owns a Russian brothel. The story has been written by Steve Knight ("Dirty Pretty Things").
