Intent on shaking up the ultimate 'sacred cow' for Jews, Israeli director Yoav Shamir embarks on a provocative - and at times irreverent - quest to answer the question, "What is anti-Semitism today?"

Defamation (Hebrew: השמצה‎; translit. Hashmatsa) is a 2009 documentary film by award-winning filmmaker Yoav Shamir. It examines antisemitism and, in particular, the way perceptions of antisemitism affect Israeli and U.S. politics. A major focus of the film is the Anti-Defamation League. Defamation won Best Documentary Feature Film at the 2009 Asia Pacific Screen Awards.
