"I just am so grateful right now," Austin told his peers inside the Beverly Hilton Hotel. "I'm in this room full of my heroes."
The 31-year-old praised his fellow nominees who "turned in the most beautiful, profound work" of the year. Austin also gave thanks to Lisa Marie Presley and Priscilla Presley for their support of a very personal film.
"Thank you for opening your hearts, your memories, your home to me," he said. I love you forever."
As producers began playing music to suggest his time was up, Austin jokingly asked for an Elvis song before thanking his co-stars and extended family for a movie experience he will never forget.
