His Oscar was accepted by Ledger's parents and sister. They accepted the Oscar on behalf of Ledger's 3-year-old daughter, Matilda.
First of all, I have to say this is ever so humbling. Just being amongst such wonderful people, such a wonderful industry. Firstly, I'd like to thank the Academy for recognizing our son's amazing work, Warner Bros. and Christopher Nolan in particular, for allowing Heath the creative license to develop and explore this crazy Joker character. To Steve Alexander, Heath's mentor, special friend and agent for 10 years. We love you, Steve.
This award tonight would've humbly validated Heath's quiet determination to be truly accepted by you all here, his peers, within an industry he so loved. Thank you.
Heath was such a compassionate and generous soul who added so much excitement and inspiration to our lives. We have been truly overwhelmed by the honor and respect being bestowed upon him with this award. Tonight, we are choosing to celebrate and be happy for what he has achieved.
Heath, we both knew what you had created in the Joker was extraordinarily special and had even talked about being here on this very day. We really wish you were, but we proudly accept this award on behalf of your beautiful Matilda. Thank you.
