Wicker Park (2004)

Synopsis
Directed by Paul McGuigan, Wicker Park follows Chicago businessman Matthew's (Josh Hartnett) return to Windy City life after having dedicated two years of his life to mourning his long lost love Lisa (Diane Kruger), who'd mysteriously vanished from his life. Things are finally looking up again for Matthew; his career is in full swing, and he's thinking of becoming engaged -- that is, until he thinks he's spotted his former lover in a restaurant. Almost immediately, Matthew puts the brakes on his marriage plans and his career in order to conduct an exhaustive search for his old flame. Obsessed, he barely notices the psychologically devastating trap his quest is leading him into -- a danger that only grows when he meets an enigmatic stranger (Rose Byrne). Wicker Park features Matthew Lillard and Jessica Paré in supporting roles. ~ Tracie Cooper, All Movie Guide
