Cooper had an odd career in 'odd ball' roles
>>Gary Cooper does not fit to me. He's a sort of amazing good looking ... Nothing more. He just doesn't look comfortable in acting ... He doesn't work to me.<<
Well he has the "key" role of the man who "gets" the girl! Gary Cooper made quite a few "oddball" and "madcap" Hollywood comedies, just as Jimmy Stewart, and Clark Gable did as well. The picture biz in the 1930's saw itself as responsible for the nation's "morale", a task hinted at by FDR's administration.
People went to the movies two or three times a week back then, if they could afford it - no TV, radio was good, but pictures Moved on the Silver Screen. After "talkies" arrived in 1928, they became the most compelling medium on the planet.
Cooper did comedy: as a "contract actor" working under the old Studio System, he had little choice in the matter. You can tell the ones he liked by the performances he gave. He performed "Design for Living", but he acted "Mr. Deeds Goes to Town!" There is quite a difference in the two roles on the screen.
Cooper is best remembered for his western persona, esp Marshall Will Kane in "HIGH NOON!" But he was also the eponoymous Casanova Brown, stared opposite Barbara Stanwyck in "Ball of Fire"
Overall I like his serious persona: For Whom the Bell Tolls, High Noon, Pride of the Yankees, Beau Geste, The Westerner, Sergeant York, The Wreck of the Mary Deare, The Fountainhead, etc. Those roles set Gary Cooper above all others.
