American Movie Classics will present three days of films by director John Ford beginning Friday as part of the Seventh Annual Film Preservation Festival. The salute to Ford includes many of his major war movies, documentaries and some of his early silent works.

The Ford bash is featured by the world premiere of the newly preserved 1941 Ford classic "How Green Was My Valley," Friday at 8 p.m., and followed by "John Ford Documentary," a portrait of the director, who in World War II served as the chief of the Navy's Field Photographic Branch.

"How Green Was My Valley" is Ford's adaptation of Richard Llewellyn's novel about a Welsh coal mining family and starred Donald Crisp, Walter Pidgeon, Maureen O'Hara, Anna Lee, Sara Allgood and Roddy McDowall. It won five Academy Awards, including best picture.
