Sienna Miller and Daniel Brühl on the Set of New BCoop Film

She is normally a cut above when it comes to style, but critically-acclaimed actress Sienna Miller was anything but as she filmed scenes for her new film in London on Sunday.

The 32 year-old star sported a sharp bob with a fringe as she recited lines on the set of forthcoming film Adam Jones. Alongside her was actor Daniel Brühl.

Adam Jones, which has a script by Steven Knight, also stars Bradley Cooper. He plays the title character: a genius cook who returns to London after a period away from the kitchen, detoxifying. Now he wants a third Michelin star, and assembles an A-list line-up to help him.

Emma Thompson, Lily James, Jamie Dornan and Alicia Vikander also star.
