A mysterious love triangle and the all-star cast of Liam Neeson, Antonio Banderas and Laura Linney can't save this ponderous romantic thriller from mediocrity. Based on a short story by novelist Bernhard Schlink (The Reader), it follows Cambridge software exec Peter (Neeson) as he uncovers details of an affair between his shoe designer wife (Linney) and her Milanese lover Ralph (Banderas). Despite being handsomely shot by director Richard Eyre (Notes on a Scandal), its plot - complete with a rather obvious twist - proves embarrassingly slight, as priggish Peter befriends and then tricks Banderas's hammy, chess-playing cad. At its heart, it's a familiar story about whether we can ever really know those we love; yet it's executed with so little passion it might as well be about car upholstery.

The story of a husband who suspects his wife of adultery, and sets out to track down the other man in her life.
