Born in Paris to Polish parents, he moved with his family back to Poland in 1937, shortly before the outbreak of World War II. He survived the Holocaust and was educated in Poland and became a director of both art house and commercial films. Polanski's first feature-length film, Knife in the Water (1962), made in Poland, was nominated for a United States Academy Award for Best Foreign Language Film but was beaten by Federico Fellini's 8½. He has since received five more Oscar nominations, along with two Baftas, four Césars, a Golden Globe Award and the Palme d'Or of the Cannes Film Festival in France. In the United Kingdom he directed three films, beginning with Repulsion (1965). In 1968 he moved to the United States, and cemented his status by directing the Oscar-winning horror film Rosemary's Baby (1968).
In 1969, Polanski's pregnant wife, Sharon Tate, was murdered while staying at Polanski's Benedict Canyon home above Los Angeles by members of the Manson Family. Following Tate's death, Polanski returned to Europe and spent much of his time in Paris and Gstaad, but did not direct another film until Macbeth (1971) in England. The following year he went to Italy to make What? (1973) and subsequently spent the next five years living near Rome. However, he traveled to Hollywood to direct Chinatown (1974). The film was nominated for eleven Academy Awards, and was a critical and box-office success. Polanski's next film, The Tenant (1976), was shot in France, and completed the "Apartment Trilogy", following Repulsion and Rosemary's Baby.
In 1977, after a photo shoot in Los Angeles, Polanski was arrested for the sexual abuse of a 13-year-old girl and pleaded guilty to the charge of unlawful sex with a minor. To avoid sentencing, Polanski fled to his home in London, and then moved on to France the following day. In September 2009, Polanski was arrested by Swiss police at the request of U.S. authorities who asked for his extradition. In July 2010, the Swiss rejected that request and instead released him from custody and declared him a "free man." Lech Wałęsa, Nobel Peace Prize laureate and former President of Poland, argued that the director "should be forgiven this one sin."
Polanski continued to make films such as The Pianist (2002), a World War II true story drama about a Jewish-Polish musician. The film won three Academy Awards including Best Director, along with numerous international awards. He also directed other films, including Oliver Twist (2005), a story which parallels his own life as a "young boy attempting to triumph over adversity.
His most recent film is The Ghost Writer (2010) (AKA The Ghost in the UK), adapted from the novel by Robert Harris, a thriller focusing on a ghostwriter working with a former British Prime Minister (loosely based on Tony Blair). It won six European Film Awards in 2010, including best movie, director, actor and screenplay.
