A family of ranchers in Montana faces off against other invaders on their land. Forry J. Smith, who plays Lloyd, is a seasoned rodeo veteran. John Dutton (Kevin Costner) often seems to “forget” his Montana accent and revert to his usual Southern California voice. Featured on WatchMojo: 10 Best Summer TV Shows You’re Not Watching (2018) I live in Darby, Montana, where most of this was filmed. Just yesterday they were filming across the street in a field with some horses and cattle. I think the show has a pretty solid story, and that’s where Costner is at his best. One thing I noticed about the first season, given my Indian-ness, is that it makes you wonder who the good guys are and who the bad guys are — maybe both sides are good and bad at the same time. I admit it’s nice to watch the footage while I’m here, the ranch is pretty close and I pass by it almost every day when I go fishing on the Bitterroot River.
