'Dark Knight' adds tribute to Ledger: The end credits of the "Batman Begins" sequel include a farewell note to Ledger.

Heath Ledger is getting a fond tribute from his collaborators on "The Dark Knight." The end credits of the "Batman Begins" sequel include a farewell note to Ledger, who died in January from an accidental overdose of prescription drugs; and to special-effects technician Conway Wickliffe, who was killed last September in a stunt-car accident. "In memory of our friends Heath Ledger & Conway Wickliffe," reads the tribute included in the credits, which went up Thursday on the Warner Bros. publicity Web site.
