Luis Trenker (*4 October 1892-April 13, 1990) was a director, architect, and actor.
His first contact with film came in 1921, when he helped director Arnold Fanck on one of his mountain films. The main actor could not perform the stunts required, and so Trenker assumed the leading role. He gradually assumed more roles on the set, and by 1928 was directing, writing and starring in his own films. The main theme of Trenker’s work was the idealization of peoples connection with their homeland and pointing out the decadence of city life. This loosely played into the hands of Nazi propagandists, who seized upon the nationalistic elements of his work.
After the war Trenker was accused of fascist opportunism but eventually the charges were dropped. In the mid 1950s he again was able to make movies, though by 1965 he had switched mainly to the documentary form. He died at the age 97 on April 13, 1990.
