Miller affected by 'Edge of Love' role

Sienna Miller has admitted that her role in new film The Edge Of Love continued to affect her once the cameras stopped rolling.

The actress told Digital Spy that her portrayal of poet Dylan Thomas's troubled wife Caitlin had a profound effect on her: "It comes home with you if you’re being someone for twelve to fourteen hours a day. Whether you like it or not... you're affected by the spirit of the person you're playing, whether it's invented or they existed."

Miller also praised the quality of the script by Keira Knightley's mother Sharman Macdonald: "It's really rare to find women who are well written, let alone two in the same film. So it was kind of bliss... and to work with Keira [was great] because we're really close."
