The Heart Of Me, a drama set in 1930s London starring Helena Bonham Carter, Olivia Williams and Paul Bettany, starts production this week in the UK.

Directed by Thaddeus O'Sullivan, the film tells the story of two sisters, one of which has an affair with the other's husband. Years later the sisters have to work out for themselves which one he loved and what it was they did to the man they both loved.

The film is backed by BBC Films, Pandora Films, Take 3/Baker Street Media Finance and the Isle of Man Film Commission.

Producer is Martin Pope, who previously produced Edinburgh favourite The Lawless Heart. Executive producers on the project, which was developed by BBC Films and Martin Pope Productions, are BBC Films' David M. Thompson and Tracey Scoffield, Keith Evans from Baker Street Media Finance and Steve Christian from the Isle of Man Film Commission.

Lucinda Coxon has scripted the picture, adapted from the novel The Echoing Grove by Rosamond Lehmann. DoP is Gyula Pados, while Michael Carlin is designing.

Director O'Sullivan's previous credits include Ordinary Decent Criminal starring Kevin Spacey and Linda Fiorentino, and Nothing Personal starring Ian Hart and Michael Gambon.

One of the UK's hottest actors, Paul Bettany recently finished Ron Howard's A Beautiful Mind opposite Russell Crowe. Early next year he starts shooting Lars von Trier's Dogville, starring Nicole Kidman.
