It's entirely plausible this is one of the 50 Worst Major Releases of All Time.
The opening scene has King Richard and his fellow marauders riding through a set that looks left over from a Joh Ford western. They are set upon by Saracens throwing rubber arrows and swinging wooden swords. A totally inept fight scene.
Then we get 15-20 minutes of camp (and campy) squabbling among Richard, the other kings, and their rabble. So boring. Saved only by the arrival of Virginia Mayo, whose line readings are so laughably bad they make the rest of the cast look like multiple Oscar winners.
It actually manages to go downhill from there.
Sanders bloviating from a sick bed. Harrison in black face. Harvey scowling in a blond wig.
Probably the only reason this didn't bankrupt the studio is that it was mostly shot on a sound stage or in front of a blue screen. They might have spent a week outside, at most, somewhere in the Baja, filming extras swinging plastic battle axes at one another.
A fascinatingly bad movie on every level. Except for Steiner's score, which is above reproach.
