New Delhi, Dec 16 : `Sex and the City' star Kim Cattrall is all set to enter 10 Downing Street and seduce British Prime Minister-just for a new film titled `The Ghost'.

In the film, the actress will be seen playing Amelia the sexy secretary of fictional UK leader Adam Lang, who is based on former real PM Tony Blair.

The 52-year-old actress 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.

And ex-Bond Pierce Brosnan will portray the PM's role in the film to be directed by Academy Award-winning filmmaker Roman Polanski.

The film is based on Robert Harris'' bestselling political thriller of the same name about Tony Blair, reports The China Daily.

It was after Roman and Kim enjoyed a business meal together that the filmmaker decided to give the role to her.

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