Based on the true story of Marty Maher, a humble Irish immigrant who rose through the ranks to become one of West Point's most beloved instructors, THE LONG GRAY LINE is a rousing tribute to a remarkable man and his way of life. Director John Ford and star Tyrone Power, themselves the sons of Irishimmigrants, bring an extra dimension of fidelity and fervor to this inspiring biography. Newly arrived in America, Maher's first job was as a waiter at West Point. Clumsy and boisterous, he quickly broke so much of the military academy's china that he was forced to join the army to repay his debts.But once enlisted, the rough-and-ready Dubliner served his adopted nation with rare dedication, establishing himself as an inspirational coach at West Point. Spanning 50 years and two world wars, thefilm shows Maher at his best, molding and motivating the young men who would become America's heroes and presidents. Filmed on location with a stellar supporting cast (including Ford favorites Maureen O'Hara, Ward Bond and Harry Carey, Jr.), THE LONG GRAY LINE is a stirring reminder of Marty Maher's proud place in history.
