Definitely in line with IMDB majority opinion here in regarding this as a mostly bombastic (especially where religion is involved), dull film with occasional flashes of interest and a couple good performances, from Juano Hernandez and the always under rated Angie Dickinson in the title role. The main problem with it flows from the egregiously bad story decision by scenarist Edward Anhalt to soft peddle the most interesting conflict, namely that of Rachel versus the tribal hierarchy symbolized by Hernandez, and instead highlight the pale, bloodless love triangle between Dickinson, Peter Finch and truly one of the dullest British actors ever to trod the boards, Roger Moore. His romantic scenes with Dickinson act as built in bathroom and snack breaks. The ones between Finch and Dickinson are a little better because Finch is a ten times better thesp than Moore but, still, you weary of them and want more scenes like the African dance that arouses Finch's and Dickinson's carnal desire...and not just for each other. Yes, the scene is on the racist side with its not so subtle message that white passions can be unhealthily aroused by dark races, but it is also quite envelope pushing for 1961, a good seven or eight years before the code was sent a packing, and I'm sure got this movie at least semi banned or censored in the American South. Give it a C plus.
PS...Hard to say whose supposed accent was worse, Finch's Belgian or Moore's American.
