First watch! Keira Knightley's new Chanel ad

Get a sneak peek at Keira Knightley's oh-so-chic advertising film for Coco Mademoiselle

We've got our hands on the very first sneak-peek at Keira Knightley's new Chanel Coco Mademoiselle advertising film, and forget biker chick, the leading lady is the epitome of biker chic in the mini movie.

Clad in a camel jumpsuit, the actress muses on her latest campaign for the fashion house as she perches beside a coordinating vintage motorbike.

Offering a tantalising glimpse of what's to come, hand-drawn illustrations of Keira's wardrobe accompany the actress's commentary on the 'Chanel superwoman', which she transforms into for the cameras.

Continuing Chanel's long tradition of teaming its muses with directors from their past, Keira reunited with Atonement's Joe Wright for the shoot, entitled Gabrielle. Back in 2005, Nicole Kidman's Parisian-themed No 5 ad had her Moulin Rouge director, Baz Luhrmann, at the helm, while Audrey Tatou's 2009 campaign was directed by Jean- Pierre Jeunet, who worked with the starlet on her breakthrough movie, Amelie.

Watch the teaser below, then click onto www.chanel.com from Monday 21st May to see the film in full.
