The first - and FATAL - mistake of this movie was the decision (I don't know whose, I suppose either the producer's or the director's) to film it in black and white. Drained of color, the deserts, skies, palaces, horses, turbans, etc. are robbed off their potential visual appeal and Sudan looks far less exotic and inviting than it could. The other problems include an uninteresting story, a thankless role for Yvonne De Carlo (although there is some heat between her and Victor Mature), and a rather disagreeable, at least for some, pro-colonial spirit. Two sequences involving "tarantula torture" are pretty much the only memorable parts of this movie. *1/2
