Downton Does Sexy: Star Sports A New Look

Downton Abbey star Joanna Froggart sported a new look at the premiere of her new movie Filth on Monday night.

We are used to seeing the actress in her dowdy uniform playing Anna Bates and this look was quite a departure.

Sporting a bodycon Herve Leger dress teamed with strappy sandals, it was difficult to see the resemblance with her Downton Abbey character.

The 33-year old opted for tousled locks and dark smoky eyes, creating quite a vampish look.

Joanne joined her co-stars James McAvoy, Joy McAvoy, Imogen Poots and Pollyanna McIntosh at the star-studded screening of the new Irvine Welsh film adaptation, with her IT director husband James Cannon by her side for moral support.

The film adaption of the book Filth, published in 1998, tells the story of immoral police officer named Bruce Robertson, who is also a sex-obsessed cocaine addict.

As well as his craving for sex and violence, Bruce is both a racist and misogynist. The novel tells of his downfall within the police force and his muddling in his colleague's private lives.

Joanne Froggatt plays Bruce's love interest Mary and the Yorkshire-born actress has said she was nervous about doing a Scottish accent in front of a mostly Scottish cast and crew.
