Among his most significant roles was Ennis Del Mar in *Brokeback Mountain* (2005), which earned him an Academy Award nomination and established him as a leading dramatic actor.

His most iconic and celebrated performance remains that of the Joker in Christopher Nolan's *The Dark Knight* (2008). For this role, characterized by terrifying intensity and physical transformation, he was posthumously awarded the Academy Award for Best Supporting Actor.
