LONDON (AP) — Writer J.K. Rowling and actress Sienna Miller gave a London courtroom a vivid picture on Thursday of the anxiety, anger and fear produced by living in the glare of Britain’s tabloid media, describing how press intrusion made them feel like prisoners in their own homes.

The creator of boy wizard Harry Potter told Britain’s media ethics inquiry that having journalists camped on her doorstep was “like being under siege and like being a hostage.” Miller said years of car chases, midnight pursuits and intimate revelations had left her feeling violated, paranoid and anxious.

“The attitude seems to be absolutely cavalier,” Rowling said. “You’re famous, you’re asking for it.”

The pair were among a diverse cast of witnesses — Hollywood star Hugh Grant, a former soccer player, a former aide to supermodel Elle Macpherson and the parents of missing and murdered children — who have described how becoming the focus of Britain’s tabloid press wreaked havoc on their lives.

Rowling said she was completely unprepared for the media attention she began to receive when her first book, “Harry Potter and the Philosopher’s Stone,” became a sensation. The seven Potter books have sold more than 450 million copies, spawned a hit movie series and propelled Rowling from struggling single mother to one of Britain’s richest people.
