I take it you don’t have Netflix or anything of the sort? Firecreek was one of the best westerns I’ve ever seen. It was one my “John-Wayne-lookalike” father’s favorites too. And he was a huge fan of westerns. Jimmy Stewart, Henry Fonda, and the beautiful Inger Stevens...
Here’s a short clip from the ending. You might want to skip it if you plan on oneday seeing the movie.
