'Variety' said that this movie was "reminiscent of the same director's Ice Cold in Alex (1958), with an ancient locomotive replacing the ambulance in that desert war story and with hordes of be-turbaned tribesmen substituting for the Nazi patrols."
This movie is equally well known by three different titles used for its theatrical release in English speaking countries. They are 'North West Frontier' (UK), 'Flame Over India' (USA) and 'Empress of India' (Australia).
The old railway seen in this picture is now abandoned and no longer used. The railroad originally traversed the northern part of the Sierra Nevadas, the mountain range in the region of the Spanish provinces of both Granada and Almería.
'DVD Talk' said of this film that it " . . . has a lot in common with John Ford's Stagecoach (1939) in that it's essentially a tale of a motley mix of Anglos confined in a train car, racing across an Indian plain trying to evade "bloodthirsty savages". It may be a blatant reworking of Stagecoach (1939) as the original story was co-written by John Ford's son Patrick Ford and Maureen O'Hara's husband Will Price. The final screenplay was adapted from a script by screenwriter Frank S. Nugent, the writer of eleven Ford films."
