On Sunday night, Frozen won the Oscar for Best Animated Feature Film.
The film's producer Peter Del Vecho and directors Jennifer Lee and Chris Buck gave a special shout out in their acceptance speech.
"We’d like to dedicate this to our guardian angel, that’s my son Ryder Buck. Thank you, Ryder.”
In August 2012, Chris Buck's son, Ryder, was diagnosed with Stage 4 testicular cancer.
Even though it was tough, Ryder didn't let this get in the way of chasing his dreams of being a successful musician.
He maintained an incredibly positive attitude, given everything he had been through.
This is him looking dapper behind Cameron Diaz at the 2012 Oscars.
His treatments worked and apparently his most recent tests showed he was cancer free.
But last October, Ryder was killed in a tragic car accident.
Over 1,200 people attended his memorial service, held on Nov. 1, 2013.
"There was so much wind beneath his wings," his mom said. "If only he could have landed."
The 23-year-old died 24 days before Frozen hit theaters, but was still proud of his dad's accomplishment.
And the feeling was mutual.
