Utilizing a couple of unusual credits - John T. Coyle as the co-director and "Pre-Production Scenes Directed and Produced by Norman Dawn" - in addition to showing the following animals "credited" below the human cast (showing here to complete the casting order for fans of animal performers, since the IMDb does not give animal credits) the following were given cast credits below the 12th billed Nina Campana; Swift Lightning - half dog & half wolf (13), Firefly, a collie (14), Buck, a St. Bernard (15) (and about the 5th film Buck, from "Call of the Wild", had poster and film credits), Toughie and Roughie, two bear cubs (15 & 16) and Winkey, the Talking raven (17.) The film finds writer Jean Williams coming to a Eskimo settlement, Topek village, in search of material for a novel. The locals fear "Swift Lightning", a half dog-half wolf that leads a vicious wolf pack.
