London, April 14: Actress Keira Knightley says she can't have a personal life while filming as the way she works is "extreme".
Knightley doesn't have time for a personal life when she's working on a film finding it hard to connect with her friends, reports femalefirst.co.uk.
Knightley refers to her recent 'Anna Karenina' schedule pointing out it was so extremely busy when she was on set that she didn't ever have the time to catch up with her close friends because of her "extreme" lifestyle.
"When I'm not working it's really about seeing as many friends as possible and making sure I'm there in their lives. The way I work is extreme. You can't really have a personal life if you're working on films all the time. There's Skype, but, really, there's just no way of doing it," she said.
"The hours are so long, you're always in a different country, you're always doing a different thing," she added.
