Heath Ledger's performance in The Dark Knight deserves:

"Late Australian actor Heath Ledger received a second posthumous award here Tuesday, as the Los Angeles Film Critics Association honored his performance in Batman blockbuster The Dark Knight," reports AFP.  "Ledger is a heavy favorite to land a best supporting actor Oscar for his spellbinding portrayal of arch-villain the Joker in the film, which shattered a series of US box office records after its release in July."

Peter Finch is the only actor to receive a post-humous Oscar, for Best Actor for Network in 1976.
