English: Director Victor Fleming, Roosevelt biographer Hermann Hagedorn, and potential Theodore Roosevelt doubles on the set of The Rough Riders. Text from back of photograph: Hermann Hagedorn (right) and Director Victor Fleming (next to right) explaining to a group of would-be doubles for "T.R." how little they really look like the late president. The men were all candidates for the role of Roosevelt in The Rough Riders, and besieged Fleming and Hagedorn, who is Roosevelt's official biographer, outside the Paramount studio.
