Festival spokesperson Claudia Wintsch confirmed Thursday that Polanski will attend the Sept. 27 tribute ceremony to accept the lifetime achievement award.
The Academy Award-winning director was freed in July 2010 from house arrest when Switzerland's government refused to extradite him to the United States where he faces charges of having sex with a 13-year-old girl in 1977.
He also served two months in prison as the Swiss government pondered his extradition.
Polanski's movements are restricted by an Interpol warrant in effect in 188 countries, but he moves freely between Switzerland and France.
