Diane Kruger's latest film role forced her to re-evaluate her life.

The actress and former model - who is in a relationship with actor Joshua Jackson - plays a French journalist kidnapped by the Taliban in 'Special Forces' and she admitted researching the role by speaking to female journalists who had suffered the same fate caused her to rethink her own career.

She said: "I researched the role for four months, interviewing female journalists who were kidnap victims, and I think it's changed me as a person. It's as though I felt quite ignorant before this, or maybe it's just part of growing up. I always thought I had a pretty accomplished life: a famous model who speaks three languages and keeps a place in Paris. This role has certainly put me in my place a little bit."

Diane, 34, spent four weeks living in the Himalayas while filming the movie and revealed it was difficult to adjust to her new living arrangements.

She explained to Gotham magazine: "It was a lot harder than I anticipated. Eighteen-hour car rides, dirt roads that are not really roads, freezing cold at night, everyone is sleep deprived, and everything is incredibly difficult and hard. I've broken down crying sometimes, but so have many of the boys.

"It was also truly breathtaking, a once-in-a-lifetime experience."
