Thomas Vinterberg is a veteran in the filmmaking business, creating "The Hunt," "The Celebration," and "Far From the Maddening Crowd." But when he took to the stage on Sunday night to accept the Oscar for Best International Film for "Another Round," the gold trophy came with a bittersweet story about how the acclaimed film was nearly derailed because of a heartbreaking personal loss.Upon accepting the Academy Award, Vinterberg talked about how much he'd imagined winning the Oscar before his speech turned a bit more somber. The Mads Mikkelsen film "Another Round," about four high school teachers who let go of their inhibitions by drinking on the job, is one of the only comedies nominated for this year's awards. As Vinterberg put it, however, this film about learning to let go came at a difficult time in his own life.In the back half of his speech, the director opens up about the tragic circumstances that unfolded just days before the film. Vinterberg says, "Mads, you gave us your finest. Not just for the film, but for my daughter as well. And I'll never forget that." What Vinterberg is referencing is the death of his daughter, Ida, who died four days into shooting for the film. In an interview with Vulture, he notes that the film was not only given the stamp of approval by Ida along the way, but it was set at her school. She was also supposed to appear in it.Related video: Red carpet ready for an Oscars unlike any other"We wanted to make a film that celebrates life... an accident on a highway took my daughter away. Someone looking into a cell phone, and we miss her and I love her," he said through tears. "If anyone dares to believe that she's here with us somehow, you'll be able to see her clapping and cheering with us." The audience remained silent until Vinterberg finished with, "Ida, this is a miracle that just happened, and you're a part of this miracle. Maybe you've been pulling some strings somewhere. This one's for you."
