Adapted for the screen for his own production company from his 1919 novel of the same name by James Oliver Kurwood, it comes as little surprise that Kurwood's book was later filmed by Disney (much changed) as 'Nikki, Wild Dog of the North' in 1961.
Chaney completists, take heed, his role is billed third, although he actually has more screen time than top-billed Lewis S. Stone (as he is indentified in the credits); the real stars being Walter L. Griffin's superb outdoor photography, the cute team of a bear called Neewa and his four-legged friend Brimstone, and leading lady Betty Blythe; in roughly that order.
The rather one-note positivity of Chaney's role has been the subject of complaints; but this was still early days and he hadn't yet become as closely associated with macabre melodrama as he soon would. I found it refreshing to see him looking so dashing and handsome and getting the girl at the end. (Usually when you see Chaney looking this bright-eyed and bushy-tailed it's at the start of a flashback and something TERRIBLE promptly happens to him; it's nice to see him get a break for once.)
