From my TIFF 2006 reviews:
DAS LEBEN DER ANDEREN, or THE LIVES OF OTHERS, turned out to be a remarkable film, set between 1984 and 1992 in East German Berlin. LIVES concerns an agent of the GDR Secret Police, the Stasi, and his mission to spy on a playwright and his actress girlfriend. With beautifully nuanced performances by the three lead cast members Martina Gedeck, Ulrich Mühe, and Sebastian Koch, and a superb script and direction by feature-film first-timer Florian Henckel von Donnersmarc, LIVES has been a huge hit in Germany and has very good potential on the art-house circuit here. This flick has "Best Foreign Film" Oscar nomination written all over it, and the sustained standing ovation it received here makes me think - even this early in the festival - that it has a good chance of winning.
(and it did).
