Brenda Blethyn, Vanessa Redgrave and Romola Garai have joined the cast of Joe Wright's
Atonement, according to Variety.
Movie stars Keira Knightley and James McAvoy, with a script by Christopher Hampton adapted from Ian McEwan's novel.
Newcomer Saoirse Ronan will play the pivotal role of a 13-year-old girl who damages the lives of all around her, as well as her own, when she accuses her sister's boyfriend of a crime he did not commit.
"Atonement" is set across the time periods - a country house in the summer of 1935; the French town of Dunkirk in 1940, scene of a catastrophic defeat for the British army; and London in 1999.
