Sienna Miller Loves Shooting Dylan Thomas Biopic in Wales 7/16/07

Sienna Miller has become an unofficial ambassador for Wales after shooting Dylan Thomas biopic The Edge of Love in the Welsh countryside.

The actress admits her busy schedule means she rarely has time to enjoy rural Britain but her latest film gave her the chance to soak in the beauty of Wales.

She explains, "It was just bliss. We were filming in Wales, running around the Welsh countryside and it was spring and the bluebells were out and the lambs were being born.

"I haven't spent a solid amount of time in the countryside of England for a while and I really loved that.

"I really realized I need the balance of that country life."

Miller was a late addition to the cast of the Dylan Thomas biopic - she was called in to replace troubled actress Lindsay Lohan after the Mean Girls star pulled out of the project.

In the film, Miller plays the poet's wife Caitlin, opposite fellow Brit Keira Knightley, whose mother Sharman MacDonald penned the screenplay for the movie.

Welsh actor Matthew Rhys plays Thomas.
