Heath Ledger's co-stars who worked with the late actor on The Dark Knight say that the Aussie was not troubled before his death or driven over the edge by his portrayal of the Joker, his character in the film.
Gary Oldman, who plays Lt. Jim Gordon in the Batman film, reveals that during filming Ledger was in high spirits and did not suffer from mood swings, sleeping problems and difficult relationships with other cast members.
