In Special Forces Diane Kruger plays a French journalist kidnapped by the Taliban in Afghanistan. Shot in Tajikistan, the French-language role is another that displays the German-born star's penchant for changing nationalities, accents and languages. Last time out, in the action thriller Unknown, the 35-year-old played a Bosnian taxi driver. Also on her increasingly illustrious CV are turns as a German actress spying for the British in Quentin Tarantino's Inglourious Basterds, and speaking German in the 2005 hit Joyeux Noel. She played a Chicago resident in Wicker Park and got her big break playing Helen opposite Brad Pitt in Troy.
"I always said that was my big dream as an actor, to be between two chairs," she says about her jump from studio films to more independent fare. "I never wanted to be typecast as a nationality. This does have the result of consistently having to do more work for a role, to be able to speak without an accent in English, to be able to speak with all different kinds of accents playing other nationalities or when I speak in French or German."
There is though, one accent the actress admits that she is afraid to try: "Scottish, oh my god, that would be hard." She adds, in English that betrays no hint of her German roots: "It's all a matter of rehearsal. You can learn any accent you want. It's a fascinating thing." Her skill with accents doesn't extend to impressions, though.
"I'm not a very good impersonator, my friends maybe, but not famous people. I can do Karl very well, Karl Lagerfeld, because he speaks the same in every language."
She doesn't give a rendition of her Lagerfeld, sadly but adds: "He's like my stepfather, I love Karl. He's the funniest person I know. He's a big inspiration actually."
Kruger got to know Lagerfeld after she began modelling in Paris, aged 15. Her move to the French capital as a teenager came after a tumultuous couple of years. Born in the tiny hamlet of Algermissen, near Hanover, her parents divorced when she was 13. Her father worked as a cinema projectionist and her mother in a bank. She stayed with her mother, pursuing a career in ballet, but after auditioning for the Royal Ballet in London an injury put paid to her dancing dreams.
Walking catwalks around the world exposed her to many different accents, but, after the initial excitement, she found the life of a model "a bit boring" and began to take a more serious interest in acting. Her love-life and career overlapped when in 2001 she married Tell No One actor and director Guillaume Canet and appeared in his directorial debut Mon Idole a year later. The couple divorced in 2006.
The actress now dates Dawson's Creek actor Joshua Jackson. The relationship and a growing interest from Hollywood in her work has led to Kruger spending more and more time in LA, although she still thinks of Paris as her home and it remains her primary base. Being in California has forced her to get into car culture. Her choice of ride is driven by environmental, not fashionable concerns .
"I sold my car in Paris and I'm driving this diesel in LA. But I want to get a hydrogen car that Mercedes are doing," she says.
To prepare for the role in Special Forces, the actress interviewed journalists who had been in war zones, an "eye- opening" experience. It gave her a greater understanding of "the lengths journalists will go to relate a story." The filming of Special Forces was far from the usual luxuries of a Hollywood set, with the actress staying in a traditional Central Asian yurt rather than a hotel. "I didn't really expect it to be so cold and arduous when I signed on to play the part", she admits.
She has had to do plenty of research for her next, more regal, role, playing Marie Antoinette in Farewell, My Queen. Based on the novel by Chantal Thomas, it follows the relationship between the queen and one of her readers during the final days of the French Revolution. It just finished shooting.
"It's directed by Benoit Jacqout and is super intellectual," she admits. "But I'm a little anxious about it because I always feel with those big historical characters you set yourself up for failure because everyone has their opinion on them. The truth is that no one really knows what she is like, and at the end of the day it's up to me and her researcher to decide who she is."
As her friendship with Lagerfeld suggests, she's never completely lost interest in modelling and, like many top actresses, adds to her income by fronting campaigns.
"From my modelling days, I have relationships with all these people and it's kind of a cool thing that I still do that as well. It's better these days as I now have more of a say in what I do and so I don't sign with people that I don't stand behind... It's very cool to be the face of a perfume, that's a very flattering thing. When Calvin Klein asked me to be the face of a perfume called Beauty I was like, 'who are you kidding?' when they told me the name. I was thinking people are going to say, 'who does she think she is from Helen of Troy to Beauty?' Then with all the work I've done for cosmetics companies too it becomes very global."
She prefers to work on campaigns for products that are aimed at the High Street: "I like the idea of accessibility, coming from a lower-middle-class background myself, I feel like beauty and products should be accessible to all women over the world." This seems to sum up Kruger. From afar and in magazines, she seems to belong to a high-end glamorous, unobtainable world, but she really is just one of the girls.
