Naomi Watts has signed to play British icon Princess Diana in Oliver Hirschbiegel's big-screen portrait Caught in Flight.

The movie is being touted to buyers in Berlin by producers Ecosse Films, the U.K. Production and finance banner behind a host of movies including Charlotte Gray, Becoming Jane and Brideshead Revisited.

Tim Haslam, the former Hanway Films chief executive, is handling worldwide sales under his upstart company Embankment Films.

Hirschbiegel directs Watts based on the screenplay by Stephen Jeffreys, with production set to begin in the U.K. This year.

Billed as a compelling portrait of the Princess of Wales during the last two years of her life, the script charts her search for personal happiness as she turns into a major international campaigner and humanitarian.
