Oliver Hirschbiegel (born 29 December 1957) is a German film director. His works include Das Experiment and the Oscar-nominated Downfall. Hirschbiegel was born in Hamburg, Germany. A Waldorf graduate, Hirschbiegel studied painting and graphic arts, later film, at the Hamburg University of Fine Arts. In 1986, he directed his first film, the made-for-TV movie Das Go! Projekt, the script for which he had written himself. He became a successful TV director, directing numerous episodes of the Tatort and Kommissar Rex series. His first theatrical release was the well-received movie Das Experiment. In 2004, he attracted world-wide attention with the film Der Untergang (released in English-speaking countries as Downfall), produced by Bernd Eichinger. It recounts Adolf Hitler's last days, and sparked an extensive debate in Germany over the portrayal of Nazi leaders. The film was a critical and commercial success, winning numerous awards and a nomination for the Academy Award for the best foreign film. One scene from the film has become the basis for a widespread viral video phenomenon. Before directing the film, he was offered the role to direct Blade: Trinity. He directed his first Hollywood feature The Invasion, which was partly re-shot by Australian director James McTeigue, at the request of the studio. Hirschbiegel directed the biographical film Diana, about Diana, Princess of Wales, which was released in September 2013. Actress Naomi Watts plays the title role. His film 13 Minutes was selected to be screened out of competition at the 65th Berlin International Film Festival. Oliver's brother Urs is an assistant director and producer.
