Il mistero del principe Valiant

Beautiful sets, great costumes and makeup.

Run of the mill script. Mediocre acting.

Bad special effects and stunts,and bad film-editing.

The special effects were truly terrible. Just stop-the-movie awful. Alligators that don't move and clearly are not alive. One alligator, clad in plate mail (huh?), shoots vertically out of the water into the air and descends down onto the stonework beside the water, where it doesn't move -while characters run about, pretending to be fearful of the clearly-lifeless, unmoving armor-clad alligator.

And lots of characters swinging Tarzan-like on ropes, slamming feet first into the villains. Except the actors are clearly hanging on ropes being moved by an overhead crane. And the ropes move slowly, as if there was great concern on the set about hurting the actors. In these scenes the villain conveniently stands in one spot until the slow-swinging good guy finally collides with him. This isn't a one-time screw-up; the slow-swinging Tarzan-bit happens over and over again.

The film editing is bad enough that it makes it hard to follow the story at spots. And the stunts and special effects kept blowing up the suspension of disbelief.

There is plenty of no-brainer action, though, and high production values on the sets and costumes. This could have been fun if it was better made.
