Revealing mistake: When they are at the Nutmar camp in the mountains, Val Kilmer tells Willow "Get on that shield!" but when they go over a 6, 7, 8 foot drop when they are sledding down the snow, you can clearly see runners on the shield.
Revealing mistake: Every once in a while Alora Dannon's hair stays put when she moves her head (fake hair attached to her bonnet!).
Revealing mistake: When Willow and Madmartigan are cornered in the ruined castle, the general with the skull helmet gets Alora and rides from the battle with her. In several shots it is very obvious that he is holding an empty blanket.
Revealing mistake: When they are escaping in the wagon and the last warrior falls off you can see the wagon's tracks as well as the thicker truck's tire tracks pulling the wagon. (00:50:20)
Revealing mistake: In the scene when Madmartigan (dressed as a woman) and Willow are being chased in the cart, they jump over a log laying across the road. One of the horse's feet lands on the log, and it squishes, like it was a hollow rubber or plastic log.
Revealing mistake: When Madmartigan is in the cage, Willow tries to stop a horse rider from riding past. The path the rider travels on looks the same in both directions. (00:30:05)
Revealing mistake: When Bavmorda and Raziel struggle for control over Sherlindrea's wand (up in the tower Ceremonial Room), lightning bolt shoot out of the wand's tip, and a monolith (among other things) is blasted. The monolith looks like it has been pieced together from cast plastic parts; the fragments' edges are too smooth.
Revealing mistake: When Cherlindrea starts levitating Elora into Willow's arms (the distanced shot, not the one where Willow takes her), you can, if faintly, see the two wires by which the bundle was pulled up.
Revealing mistake: After Madmartigan falls off the sliding shield, brown haired Willow is replaced by a stunt with black hair.
Revealing mistake: When Madmartigan and Willow are about to crash against a rock and when they're speeding downhill, Mad's been replaced by an obvious stunt holding an ugly doll. (01:15:19)
Revealing mistake: Madmartigan is asked by a man if he wants "to breed" and he rejects him and turns around. Right then you'll notice that Elora's been replaced by an obvious doll. (00:48:03)
Revealing mistake: Whenever Rool and Franjean have been blue-screened into the movie, the ground does not react to their movements. This is particularly noticeable when they are standing by the base of a tree, surrounded with dirt and pebbles, and when the entire group of brownies are dragging Willow and Meegosh through the dirt.
Revealing mistake: Willow kills the walking cauldron (a stop-motion superimposed image) with a farmer's fork, but he's very obviously just mimicking and the fork is not pinching the cauldron at all.
Revealing mistake: Madmartigan kicks a baddie but his foot misses by far, despite the thump being heard. (01:31:44)
Revealing mistake: During a battle at the castle where a troll turns into a huge 2-headed monster, Willow charges with a sword. However, the sword wobbles; it's a rubber sword.
Answer: Bavmorda's ritual was the Ritual of Obliteration - a spell that is used to destroy a living spirit's essence or soul. Presuambly if she'd just killed Elora, the soul would have been later reborn into another baby.
