Another reviewer remarked that The Painted Hills was "startlingly dark" for a Lassie film. After watching it I would have to agree. It's also while not Citizen Kane material not as bad as some make it out.
I have a theory on that. This is supposed to be a family film, but Bruce Cowling isn't a family film type villain. He's an ordinary guy who succumbs to the traditions of gold fever. Fred C. Dobbs never got as psychotic as this guy when he decides he doesn't want to split the strike that his partner Paul Kelly has uncovered, neither with Kelly or Ann Doran widow of a third partner who has a son Gary Gray.
Lassie is called Shep in this film, but it's our beloved collie just the same. Shep is the only witness to what happened to Kelly. Man can't prove anything that can stand up in a court of law, but the collie knows the story and the collie settles accounts in a manner worthy of a Corleone.
The Painted Hills is from MGM's B picture unit. I'd give this one a look, not as bad as some reviewers make it out.
