Early "B" John Wayne western with Duke playing a cowboy who comes to a ghost town where a bunch of bad hombres are looking for gold. There's a mysterious character named The Phantom trying to scare people away. Duke even rides a horse named Duke! He also has a black sidekick named Clarence that is the stereotypical "afraid of spooks" caricature of the time. So some viewers might take offense to that. It's a mix of genres and since Wayne never did any proper horror films, this is about as close as you're likely to get to seeing him in one. There are some attempts at horror/mystery atmosphere but it's pretty much a routine western of its type. Worth seeing for a baby-faced John Wayne and some good old school stunt work. Erville Alderson is a spooky plus. The original Maltese Falcon statuette from the 1931 film can be seen atop an organ in one scene. Pretty cool!
