Gene Autry discovered Gail Davis (did you guess right?). He thought she was so good that he featured her in about 20 of his movies, 30 episodes of his own tv show and then, of course, he created and produced the "Annie Oakley" tv show for her, too. She was such a good rider and trick shot artist that she even performed in Gene Autry's travelling rodeo!
Someone asked her once if she would ever do some other character and Gail Davis said "So far as I'm concerned, I'm going to be Annie Oakley for the rest of my born days". And she did just that. She later became a manager of other celebrities.
