Before he begins work on "Scooby Doo 2", Matthew Lillard will complete "Wicker Park" for director Paul McGuigan. Based on the 1996 Giles Mimouni-directed "L’Appartement," "Wicker" is an intense, Hitchcockian psychological drama about a man (Josh Hartnett) and his obsessive search for a lost love from his past that ends up uncovering the twisted machinations of an eccentric secret admirer. Lillard will portray Hartnett’s character’s best friend in the film. Australia’s Rose Byrne (Two Hands) and Diane Kruger star as film’s two female leads.
