Western star Lee Van Cleef is cast here in the title role, an Indian (!) officer in the Union Army. Clean shaven, wearing a toupee, and caked under more makeup than usual, Van Cleef is on the case when an Indian agent (Luis Induni) is killed. The agents' dying words are "April morning", and Van Cleef must solve the mystery behind this phrase. Among the characters he encounters are Griffin (Stuart Whitman), a gun runner, Griffins' fiancée Maude (ever lovely Carroll Baker), and a pair of thugs, Moon (Percy Herbert) & Snake (Tony Vogel).
The prospect of Van Cleef playing an Indian is the main drawing card of this decent enough but unremarkable film. It's adequately directed by Alexander Singer, a veteran of mostly TV, and scored well enough, by Dolores Claman, but it's also choppily edited, and the story (based on a novel by S.E. Whitman), isn't told in a particularly interesting way (despite the presence of top screenwriter Philip Yordan). What does help, to a degree, is a certain irreverence at times, and vivid location shooting in Spain. More squeamish viewers may appreciate the fact that it's violent without being particularly gory.
The mostly European cast is entertaining enough to watch. Whitman and Baker are fine, but "Captain Apache" is first and foremost a Van Cleef vehicle. He offers a typically stylish and charismatic performance, and, in one hilariously absurd scene, must suck in his gut when he's made to disrobe in front of an Indian chief.
Unmemorable overall, but it's still recommended if one is a fan of the star.
Six out of 10.
