I must admit this Italian Medieval 'pot boiler ' intrigued me with its title. Basically I'd never heard of it.
Mel Ferrer is the hero in this entertaining slab of Russian / Polish timescale which resembles John Wayne's 'The Conqueror ' in more ways than one.
Unfortunately there is no charge of the 'Black Lancers ' & scant reference to them either.
There is a battle staged at the end which is somewhat confused.
The DVD release is in its widescreen presentation with adequate colour resolution.
Overall an entertaining romp through European history much forgotten.
