Kim Cattrall will seduce the British Prime Minister in new movie "The Ghost." The 52-year-old actress will play Amelia, the sexy secretary of fictional U.K. leader Adam Lang, who is based on former real PM Tony Blair, portrayed by Pierce Brosnan.

Kim will appear alongside 37-year-old Scottish actor Ewan McGregor, who plays the writer brought in to ghost Lang's memoirs, and 40-year-old British actress Olivia Williams, who plays Lang's manipulative wife Ruth.

Academy Award-winning filmmaker Roman Polanski will direct the movie, which is based on Robert Harris' bestselling political thriller of the same name about the ex-occupants of No. 10 Downing Street.

Roman decided to hand Kim the sought-after part after they enjoyed a business meal together.

The film's executive producer Timothy Burrill said: "They had a lovely lunch and fell in love with each other, in a manner of speaking."

It's not Kim's first political conquest. When the actress was 25, she was romantically linked to former Canadian Prime Minister Pierre Trudeau.
