Organisers say the 78-year-old will attend the gala to receive his award which he was set to pick up in 2009.
Swiss police arrested Polanski on his arrival in the country over his 1977 US conviction for having sex with a 13-year-old girl.
He was held for 10 months before Swiss courts decided not to extradite him.
The tribute ceremony to present Polanski with his lifetime achievement award is due to be held on 27 September.
Directors of the Zurich Film Festival, Karl Spoerri and Nadja Schildknecht, said: "We are especially proud to welcome Roman Polanski this year to receive his award.
"We have always been tremendous admirers of his work and we are delighted that we will soon be able to express this to him in person," they added.
The Zurich Film Festival is taking place from 22 September to 2 October. » | Friday, September 16, 2011
