I saw this by chance on 'movies for men' yesterday.
It seemed to be an Italian or Spanish attempt to exploit the big Cid movie and the vogue for historical costume dramas of the time.
Whilst interesting to watch it hardly stands out as an epic film. The characterisations are weak and superficial, the sword fights are lame and over-contrived and, boy, are there a lot of horses.
Horses here, there and everywhere...the director must have commissioned an expensive troop of army cavalry as he uses them EVERYWHERE.
Oh, BTW, the wigs are out of this world.
Worth a watch to catch the flavour of cinema in those times.
