Deadline is reporting that ATO Pictures has picked up the rights to distribute James Marsh's political thriller Shadow Dancer, starring Andrea Riseborough as a Northern Irish woman involved with the IRA coerced into becoming an informant by a persuasive MI5 agent, played by Clive Owen.

Adapted by Tom Bradby from his own novel, the film also stars Gillian Anderson, Aidan Gillen and Domhnall Gleeson. Marsh previously directed the Oscar-winning doc Man on Wire and last year's Sundance opener Project Nim.
