While I would not call this movie excellent, or even great, it's really pretty good. I have to admire that they really didn't use a set, it was mostly shot outdoors. Yes, California had to substitute for Arabia, but oh well. I'm not a horse lover, but the horses were beautiful. The only thing I can say I didn't care for was the hero, Tamerlane, for much of the movie, appeared to be much more interested in acquiring & taming the black stallion, rather than acquiring & taming the heroine, Princess Tanya. She seemed to be the instigator of their relationship, poking & prodding him along the way. Funny thing, Arab princesses aren't typically flame haired, so I was surprised they didn't issue her a dark wig, since I don't think she's ever colored her hair a different color for a movie.
All in all, on the 1-10 scale, I'd put this movie at about an 8.5-9.0. Maureen's costumes were gorgeous (her costumes always were), the acting is adequate considering this movie had pretty basic plot, the horses looked amazing, and Jeff Chandler's build was stunning. Would like to have seen some swordfighting, some swashbuckling would have been in order. Thus the 4 star rating. See my review of 'Bagdad', the 'companion' movie to 'Flame'.
