Keira Knightley has admitted that she used to have "no life" outside of her acting career.
The Atonement star - who is engaged to Klaxons rocker James Righton - revealed to Vogue magazine that she struggled with her fame after roles in films like Bend It Like Beckham and the Pirates Of The Caribbean movies.
The 27-year-old, who made her movie debut in thriller Innocent Lies at the age of 10, said: "I literally had no life outside of acting, and I just wanted to go off and not be 'on' all the time, not be photographed, not..."
She continued: "I once went to the Glastonbury music festival and was completely surrounded by packs of paparazzi the entire time, so I ended up sitting in a trailer, unable to go out."
Keira, who stars in the new Anna Karenina film alongside fellow Brit Jude Law, also opened up about her movie choices, revealing she likes to play characters who have "bite".
She said: "I'm not really interested in the kinds of women who just take off their clothes or have a sex scene and then say something cool."
The actress said of her latest character: "She is both a villain and a heroine. She can be incredibly vain and manipulative. She is somebody who breaks her own moral code, and yet the shame and disgust she lives with because of that make her fascinating."
The October issue of Vogue goes on sale on September 25.
