Miller acts on photo 'harassment'

Sienna Miller will play Maid Marian in a film remake of Robin Hood

Actress Sienna Miller's life has been made intolerable because of a "campaign of harassment" by photographers, her lawyer has told London's High Court.

Miller, 26, is taking legal action against photo agency Big Pictures (UK) Limited and its founder, Darryn Lyons.

The actress claimed they are guilty of invasion of privacy and harassment.

She has been caused "substantial alarm, fear and enormous distress" by their conduct, her lawyer David Sherborne said at a preliminary hearing.

The court heard Miller, who did not attend the hearing, was chased while driving and there were "other forms of physical and verbal intimidation or abuse in their attempts to obtain photographs of her".

Mr Lyons and the agency are contesting the claims.

Miller has starred in movies such as Alfie and Layer Cake and is the ex-girlfriend of Jude Law.

Last month, she accepted �15,000 damages in an out-of-court settlement against the Daily Star over a paparazzi photo.
