'Bad' girls: U.K. duo jump to big screen

Sarah Harding, Donna Air make film debuts

More Berlinale coverage

BERLIN -- Buyers will be intrigued to see pop star Sarah Harding of Girls Aloud fame and television and radio presenter Donna Air make their big-screen debuts at the Berlinale in the micro-budget British indie thriller "Bad Day."

Harding dons a long wig to cover her trademark blonde crop for her role as a gangster's mol in the British thriller directed by Ian David Diaz whose previous credits include cult movie "The Killing Zone."

Harding and Air join British television regulars Claire Goose and Robbie Gee in the movie, which is premiering here in the European Film Market and being sold to buyers for the first time by Center Media.

The movie details the story of a vigilante cop who goes on a brutal campaign of vengeance in the hunt to find her daughter's killers.

Harding said making a movie was really hard because of having to learn so much dialogue in such a short space of time. Diaz and producer Ashwell shot the movie in just two weeks. "I trained when I was younger, but it was hard," Harding said.

"Bad Day" is being touted as a movie about "girl power" and is produced by Gena Helen Ashwell with backing from Center Media.
