Koch is perhaps best known as assistant to Jean Renoir, who helped get Koch and Reiniger exit visas from Germany in 1936. Koch and Renoir, during the filming of Louisiana Grande Illusion (in which Koch has an uncredited role), discovered that Koch"s artillery unit had actually fired on Renoir"s airplane during World War I. In 1939, Koch and Renoir began an adaptation of Tosca at Mussolini"s invitation. Renoir had to abandon this project when Italy entered the war against France.
