This just became one of my favorite Randolph Scott movies.
First, there's an intelligent script by Russell Hughes, who wrote for some good radio shows like "Nightbeat" and Alan Ladd's "Box 13", as well as such films as Anthony Mann's "Last Frontier", Delmer Daves' "Jubal", and even the best of the giant-bug movies, "Them".
Then, there's the look and feel of the film. Director Andre De Toth and his great cinematographer Bert Glennon (who had done remarkable work with the likes of Josef von Sternberg and John Ford) light and shoot for realism and emotional impact. Glennon had also shot "Man Behind the Gun" (available on the flip side of this DVD), so I suppose director Felix Feist could be blamed for that film's phony-looking stage sets. Here, in "Thunder... ", a barroom scene looks like it was shot in a real barroom (foreshadowing Clint Eastwood's "natural lighting" technique by decades) and exteriors are shot outdoors. To be fair, the Feist film may have had budget or producer issues, but given that film's potential (dealing with water rights, corrupt politicians, the possible secession of southern California, even the semi-legendary Joaquin Murrietta as a supporting character) it still seems like a typical, entertaining, 40's-style B-movie. "Thunder...", released the same year, 1953, seems more forward-looking, more compelling, more of the age of the "adult" Westerns, even though the literally flag-waving ending with its narrative paean to the great state of Texas kind of pulls us back to B-movie-land.
