Los Angeles, Aug 22 (IANS) Actress Kristen Stewart, Chanel’s newest campaign model, will star in a film directed by designer Karl Lagerfeld for an upcoming show of the French fashion house.

The story, conceived by Lagerfeld, offers a fictional, behind-the-scenes look at a biopic in the making about founder Gabrielle Chanel, reports variety.com.

Stewart portrays an actress impersonating the designer as a young woman. Geraldine Chaplin, who has played Chanel in previous Lagerfeld films, is in the movie as well. Lagerfeld filmed the project last month in two days at director Luc Besson’s Paris studio.

Lagerfeld said Stewart “played it really, really mean.”

“You only see her in tests and she’s complaining about everything. She’s mean with the director; mean with the producer,” he told fashion industry trade magazine WWD.

Lagerfeld is the head designer and creative director of Chanel, Italian house Fendi and his own label.
