Special to the Daily Eagle County filmmaker Chris Anthony thought he was being spammed when the email arrived, telling him his documentary has been accepted into the Cannes World Film Festival. The idea for “Mission Mt. Mangart,” a film about the U.S. Army’s 10th Mountain Division ski troopers in World War II, came to Anthony six years ago. Since then he’s been working non-stop in his efforts to produce a documentary about a few of the discoveries he made in Europe about the 10th Mountain Division. “Like most people, I thought the whole story of the 10th took place at Camp Hale, Mt. Belevedere and Riva Ridge,” Anthony said. “But I discovered that there’s a lot more to their story.”
