Though the star of earlier not-so-great films like A Knight's Tale and The Order, Ledger redefined himself as an actor with the 2005 film Brokeback Mountain. Some other great work followed. After the jump, three clips from some of his higher-profile, crticially lauded movies (and a teaser for the film The Dark Knight, in which he plays the Joker.)
