A former Mack Sennett bathing beauty and Stan Laurel's co-star in the 1918 two-reeler Whose Zoo?, blonde Kathleen O'Connor came into her own as Tom Mix's leading lady in five Westerns from 1918-1921. She also appeared in serials -- The Lion Man (1919) with Jack Perrin and The Midnight Man (1920) with prizefighter James J. Corbett -- and played the ingenue in William S. Hart's Wild Bill Hickock (1923). O'Connor retired from acting in February of 1924 to marry Tom Mix's director, Lynn F. Reynolds, a rather stormy union that ended with Reynolds' sudden death in 1927.
