Defiance is a 2008 World War II film directed by Edward Zwick set during the occupation of Belarus by Nazi Germany. The screenplay by Clayton Frohman and Zwick was based on Nechama Tec's 1993 book Defiance: The Bielski Partisans, an account of the Bielski partisans, a group led by Polish Jewish brothers who saved and recruited Jews in Belarus during the Second World War. The film stars Daniel Craig as Tuvia Bielski, Liev Schreiber as Zus Bielski, Jamie Bell as Asael Bielski, and George MacKay as Aron Bielski.
Production began in early September 2007. After a limited release, e.g. Los Angeles, New York City, in the United States on December 31, 2008 it went into general release worldwide in January and February 2009.
The film opens with on-screen text stating: "A true story". It is August 1941, and Nazi Einsatzgruppen are sweeping through Eastern Europe, systematically killing Jews. Among the survivors not killed or restricted to ghettoes are the Polish Jewish Bielski brothers: Tuvia (Daniel Craig), Zus (Liev Schreiber), Asael (Jamie Bell), and Aron (George MacKay). Their parents are dead, slain by the local police under orders from the occupying Germans. The brothers flee to the Naliboki forest, vowing to avenge their parents.
