A pleasingly plump ingenue of the late 1910s, Mabel Julienne Scott played the nominal leading lady in Roscoe "Fatty" Arbuckle's serio-comic The Round-Up (1920). Scott's love interest in that film was actor/director Tom Forman and Forman was with her again that same year in The Sea Wolf, the second screen version of the Jack London classic. 1920 was a banner year for Scott but fame proved fleeting and she was playing minor roles by the end of the decade. A graduate of Northwestern Conservatory, Scott was the sister of William Scott, a juvenile actor best known for playing Mary Pickford's tenement beau in Amarilly of Clothes-Line Alley (1918). ~ Hans J.
