Nicole Kidman has dedicated her new film about famed war reporter Martha Gellhorn to late journalist Marie Colvin, who was killed in Syria earlier this year (12).

The Australia star plays the writer in Hemingway & Gellhorn opposite Clive Owen as her husband Ernest Hemingway, and she premiered the movie at the Cannes Film Festival in France this week (ends27May12).

Kidman told reporters at the event that she is dedicating her performance to tragic Colvin, who died while covering the conflict in Syria in February (12).

She says, "I really see her (Colvin) as someone similar to Martha. These women are still rare and Martha was the first."
