Roman Polanski returned to the Cannes Film Festival, where he presented a short film sponsored by Prada.

Before a screening of a restored version of his 1979 film "Tess," starring Nastassja Kinski, the Polish director showed the short, titled "A Therapy." It stars Ben Kingsley and Helena Bonham Carter and was created as a high-quality commercial for Prada.

That was a relative disappointment for festival-goers who had been teased that Polanski would preview a new film.

The festival earlier screened the documentary "Roman Polanski: A Film Memoir," which features conversations between Polanski and his friend Andrew Braunsberg about his U.S. arrest in 1977 for unlawful sex with an underage girl and his subsequent flight to France before sentencing.

Polanski, who currently lives in Paris, was in 2009 arrested in Switzerland to be extradited to the United States. The Swiss eventually rejected the request.

Polanski won the Cannes' Palme d'Or in 2002 for "The Pianist."
