The 76-year-old director, who is in custody in Zurich, was arrested three days ago because US prosecutors want to extradite him so that he can be sentenced for having unlawful sex with a 13-year-old girl in 1977.
Polanski had pleaded guilty at the time but then avoided being sentenced by escaping out of the country and has since been living in France some of the time since then. He holds a French-Polish citizenship.
Polanski was arrested on Saturday after arriving in Zurich to collect an award.
The famous director has been visited in prison by French and Polish diplomats.
