Heath Ledger‘s father Kim was all smiles Wednesday at LAX. He and his entire family flew in from Perth, Australia to attend the Academy Awards on Sunday — and if Heath wins, his dad told reporters he may say a few words on behalf of his son. He said he didn’t want to take anything for granted, but that if his son gets the award, the Oscar will eventually go to his daughter Matilda. Ledger is nominated for Best Supporting Actor for his performance as The Joker in The Dark Knight. He died just over a year ago at the age of 28 from an accidental overdose of prescription pills. The mother of his daughter, actress Michelle Williams, is also scheduled to attend the ceremony.
