Man's Best Friend also happens to be one of Hollywood's Best Friends as Deborah Painter examines the contribution to the silver screen by lovable, talented and brave stars of the cinema: Hollywood's Top Dogs. Their bark was silent but their impact was great as you meet the canine stars of the early silent movies and then trot through time with the likes of Peter the Great, Rin-Tin-Tin, Ace, Flash, Lightnin', Lad, Lassie and Benji. These heroes are brave, pure and offer unequivocal love and devotion, and in today's depressing world, it's nice to find some real heroes of the silver screen.
