Heath Ledger, Oscar-nominated for his role as a gay rancher in Brokeback Mountain, was found dead in his New York city apartment on Tuesday. Early reports indicated that prescription drugs may have been involved though police believed the death was not a suicide.

Commentary: The Australian-born actor had already established himself as a force in the industry. His brilliant portrayal of Ennis Del Mar, a man tormented by his gay feelings, helped the non-mainstream type movie Brokeback become a major success. Ledger had also shown his comedic talents in "10 Things I Hate About You" and had recently completed the latest Batman flick playing the role of "The Joker." He was 28.
