For seventy-one minutes the film manages to fit in the deteriorating security situation in Tombstone as the camera flashes to the street for all the shootouts and horseplay. Compared to My Darling Clementine, this one is more easy going. Cesar Romero captures best acting over Vic Mature in the role of Doc Holliday, IMHO if only because Mature's part seemed overwrought, and the part of Holliday seems to fit Romero in a decisively more real way. Even still, the script in Frontier Marshal still caricatures Holliday as overly emotional, especially in the scenes in the saloon where he's purposely drinking himself to death because ex-flame Nancy Kelly comes in on the stage. Still, Romero was a great actor, and his scenes with Randolph Scott as Earp are a nice mix of two actors who had real naturalness. The B&W photography (Charles Clarke) stands out throughout and all the scenes in this movie are well assembled. It is over before you know it.
