High-quality Austrian films, which have won more and more critical acclaim in recent years, are usually produced by small production companies, often in co-production with other countries. Examples of this are "The Piano Teacher" and "Caché" by Michael Haneke, probably the most famous Austrian director at the current time. Other successful Austrian films (wholly Austrian and co-productions) since 2000 are We Feed the World (Erwin Wagenhofer), Darwin's Nightmare (Hubert Sauper), Calling Hedy Lamarr (Georg Misch), "Grbavica" (Jasmila Žbanić), Slumming (Michael Glawogger), Silentium and Komm, süßer Tod (both Wolfgang Murnberger), The Edukators (Hans Weingartner) and Dog Days (Ulrich Seidl). Other notable contemporary directors are Barbara Albert, Andrea Maria Dusl, Elisabeth Scharang, Jessica Hausner, Stefan Ruzowitzky, Ruth Mader, Kurt Palm, Nikolaus Geyrhalter and, resident in the U.S., Robert Dornhelm.
