Rebecca Hall and Guy Pearce have been cast in spy film Shadow Dancers.

Set to be directed by James Marsh (Man on Wire), Shadow Dancers is based on the novel of the same name by Tom Bradby, who also penned the adapted screenplay.

Shadow Dancers centers on a young woman (Hall), a former IRA terrorist turned informer for Blighty’s MI5. Her brothers are both heavily involved with the IRA and her husband was killed by Brit security forces. But when she is arrested over an aborted bombing attempt in London, she is forced to reveal her past if she wishes to see her children again.

Shooting will commence mid-2011.
