The Rosemary's Baby director is currently under house arrest in Switzerland as American prosecutors attempt to force him back to the States to face sentencing for having unlawful sex with a 13-year-old girl in 1977.
Several high-profile figures have already spoken out in support of the movie-maker, including Johnny Depp, Pierce Brosnan and Ewan McGregor, and Polanski is now hoping Obama will join them - he has allegedly written to the U.S. President asking to be spared jail.
French magazine L'Express reports the country's leader President Nicolas Sarkozy - who is backing Polanski's bid for freedom - "played the postman" and delivered the hand-written note to Obama earlier this month (Apr10).
Journalists at the publication wrote, "In an astonishing act of backroom diplomacy, Nicolas Sarkozy hand-delivered a letter from Roman Polanski to Barack Obama last week on the sidelines of the anti-nuclear proliferation summit in Washington."
Polanski fled to France in 1978 after pleading guilty to a charge of unlawful sex with a minor. He was arrested by Swiss officials last September (09) after arriving in the country to attend a film festival in Zurich.
