Prime Suspect: The Final Act (TV) (2006; UK/USA; Colour; 182m) ∗∗∗∗ d. Philip Martin; w. Frank Deasy; ph. Julian Court; m. Nicholas Hooper. Cast: Helen Mirren, Stephen Tompkinson, Laura Greenwood, Eve Best, Gary Lewis, Katy Murphy, Frank Finlay, Tom Bell, Robert Pugh, Brendan Coyle, Robbie Gee, Russell Mabey. Approaching retirement, Jane Tennison investigates the murder of a missing girl. But the cracks soon begin to show as Jane struggles with an alcohol problem and the death of her father. Final installment in the series is a relentlessly downbeat affair. Mirren delivers a superb performance and the production values are excellent and authentic. There is the occasional contrivance and the finale seems rushed after over three hours of twists and turns. But this is still an absorbing last hurrah for one of TV’s great detectives.
