It is the second sudden death of a German star in as many months. In June, the 38-year-old Frank Giering, whose performances in Michael Haneke's original "Funny Games" and Sebastian Schipper's "Gigantics" marked him as one of his generation's leading lights, died of organ failure following a colic attack.
The cause of Schmieder's death is still unclear. His agent, Birgit Vogel, would only confirm that Schmieder had been found dead in a hotel bed in the Italian town of Livigno. The actor, an amateur sports enthusiast, had been taking part in the mountain biking race, Bike Transalp. A teammate found his body.
Schmieder had small supporting roles in feature films including the Oscar-nominated "Downfall" (2004) and Bavarian comedy "Brandner Kaspar" (2008) but it was in TV drama that he made his name.
