The parents and sister of Heath Ledger were out in full force last night to see the late actor’s final completed film The Dark Knight premiere in New York.

Father Kim, mother Sally and sister Kate flew in from the Joker's native Perth, Australia to attend the screening at the AMC Loews Lincoln Square IMAX.

However, the Ledger family did not walk the red carpet.

A movie source reveals the family has already seen the movie, which has been dedicated to Heath Ledger.

Ledger died from an accidental drug overdose in January.
