Carey Mulligan is set to star as a Vietnam war correspondent in the film On the Other Side. Based on the book 'On the Other Side: 23 Days with the Vietcong', the true story centers on Kate Webb, a trailblazing journalist for UPI who would pave the way for all the female war correspondents that came after her. Surviving fierce battles and 23 days of captivity, she emerged from the jungles of Cambodia armed with one of the most unlikely stories to come out of the Vietnam War. Mulligan, whose memorable turns in The Great Gatsby, An Education and Inside Llewyn Davis helped catapult her to the top of director wish lists, also will produce the drama.
