According to Wikipedia: "Otto Lang (21 January 1908 – 30 January 2006) was a skier and pioneer ski instructor from Bosnia and Herzegovina, who lived and worked in the United States. After teaching skiing at a variety of smaller resorts in Austria, he joined the Hannes Schneider Ski School in St. Anton am Arlberg, one of the most prestigious ski schools of the era. Like many instructors who taught Schneider's Arlberg Method, Lang was eventually offered a chance to teach in the U.S., at Pecketts' on Sugar Hill in the White Mountains of New Hampshire. He later moved out west and founded ski schools on Mount Rainier, Mount Baker and Mount Hood.
Lang was hired by Darryl F. Zanuck to assist with the ski sequences of the 1941 movie Sun Valley Serenade starring Sonja Henie, which ultimately led to his cinematic work. Some of his notable feature films include Call Northside 777 (1948 - producer), 5 Fingers (1952 - producer), Love is a Many-Splendored Thing (1955 - director for scenes filmed in Hong Kong), Search for Paradise (working title The Search for Shangri-La) (1956 - director) and Tora! Tora! Tora! (1970 - associate producer of the Japanese segments). He produced the short films Vesuvius Express (1953), The First Piano Quartette (1954) and Jet Carrier (1954) nominated for Academy Awards.
