Thundering Frontier (1940)

Saturday matinee energyCowboy crooner interludesCompetent but forgettable

Overview

Western

After a handful of non-formula westerns, Charles Starrett returned to the mixture as before in Thundering Frontier. Starrett plays Jim Fillmore, kind to old ladies, small animals and heroine Norma Belknap (Iris Meredith). In contrast, the villains are kind to no one, least of all struggling building contractor Square Deal Scottie (Alex Callam), whose projects are continually targeted for demolition and his payroll is forever being stolen at gunpoint. A good 25 percent of the film's running time is given over to Bob Nolan and the Sons of the Pioneers, whose C&W croonings are pleasant but a bit much. One of the film's few surprises is that Starrett's perennial screen sparring partner Dick Curtis isn't one of the bad guys.

Deep Dive

Trivia, insights & behind the scenes

Trivia

The Sons of the Pioneers were already western music royalty by 1940—this was early Roy Rogers adjacent content before he became the bigger star.

Insight

Director D. Ross Lederman reportedly shot this in under a week—explains why 25% is musical padding and the 'landslide' is mostly dust and yelling.
