Film-maker Roman Polanski, who is in Poland to make a new film, has said he will cooperate with Polish authorities as part of a US request for his extradition over a 1977 child sex crime conviction.

The Polish prosecutor-general’s office said last week it planned to question Polanski, who was born to Polish parents but lives in France, after it received the request for his extradition.

“I am here mainly for preparations for a film I want to make this year,” Polanski told TVN24 in an interview. “I know that an extradition request has come and, of course, I will undergo the procedure and we will see. I trust the Polish judiciary system. I hope everything will be all right.”

Polanski, 81, is viewed by many Poles as one of their greatest living cultural figures. Internationally renowned for such films as Chinatown and The Pianist, Polanski is now in Poland to make a film about the Dreyfus affair, a political scandal that shook France more than a century ago.

I trust the Polish judiciary system

Last October, prosecutors in the Polish city of Krakow interviewed him in connection with a US warrant over the 1977 conviction. They said there were no grounds to arrest him and that they would await a US extradition request before deciding on any further steps.

The film-maker pleaded guilty in 1977 to having unlawful sex with 13-year-old Samantha Geimer during a photo shoot in Los Angeles, fuelled by champagne and drugs. He served 42 days in jail as part of a 90-day plea bargain.

He fled the US the following year, believing the judge hearing his case could overrule the deal and put him in jail for years.

In 2009, Polanski was arrested in the Swiss city of Zurich on the US warrant and placed under house arrest. He was freed in 2010 after Swiss authorities decided not to extradite him to the US.
