DVD & Blu-ray review: Shadow Dancer (15)

'Shadow Dancer' centres on Colette (Andrea Riseborough, left), an inept IRA terrorist who is captured by MI5 after bungling a London Tube bombing

James Marsh's determinedly downbeat tale, set in 1993 during the Northern Ireland peace process, centres on Colette (Andrea Riseborough, excellent), an inept IRA terrorist who is captured by MI5 after bungling a London Tube bombing.

Clive Owen's earnest agent offers her a stark choice: face a long prison sentence or return to Belfast and snitch on her brothers (Domhnall Gleeson and Aidan Gillen). She plumps for the latter as she has a young son to care for. A tense, intelligent political thriller about the Troubles from the director of Man on Wire.
