Chuka is an unusual and unsatisfying Western with a plot that several times reminds one of Beau Geste. It starts with the US Cavalry retrieving their comrades' bodies at a fort that has been overwhelmed by Indians and then flashes back to portray the events that led up to the massacre.
John Mills usually plays a sympathetic character but as Colonel Valois he has no redeeming feature at all, even at the end he stands apparently helpless as his ragtag soldiers fight off the Indian attack. (One wonders why a colonel has such a small command, which seems to total barely 40 men, and the fort itself is small enough to fit conveniently into a studio.) It is hard to find much to like about most of the cast, but then the members are playing unlikeable people. Rod Taylor as the gunslinger Chaka shows his good side in the opening scenes when he offers his food to starving Indians but drives a hard bargain when his scouting expertise is needed. Louis Hayward, looking a bit like the British character actor Terry-Thomas, pays for the services of an Indian girl. Only Ernest Borgnine, appearing larger than one usually visualises him, makes much of a screen impact, and his character is one of the few who seems not to have an unfortunate past.
The two Mexican ladies marooned at the post after rashly travelling across country in a stagecoach are an intrusion into the plot (but then I often groan at the contrived introduction of glamorous women into an environment that in real life would be all-male).
All in all, a disappointing oddity.
