Continuity mistake: The size and look of the lump of mud and grass Elora floats on down the river differ between several shots. (00:05:00)
Continuity mistake: When Kaiya asks Willow if they should tell the Village Council about Elora, as Willow passes Kaiya, her hand is resting beside Elora. When it cuts to a close-up of Elora, Kaiya's arm is suddenly supporting Elora's head. (00:08:35)
Continuity mistake: When they've found Madmartigan in the cage, Burglekutt decides to leave. Willow then places his hand on Vohnkar's shoulder and puts it down when Burglekutt says "It's not his decision". When it cuts, Willow's hand is back on Vohnkar's shoulder. (00:27:25)
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)
Continuity mistake: While Madmartigan is caged up and Willow says "And supposed you're a warrior", you see Madmartigan playing with the chain in his hand. When it cuts, his hand is holding onto the cage. (00:30:20)
Continuity mistake: When they let Madmartigan out of the cage he grabs Elora and swings her through the air. It cuts to a close-up of her and you can see Madmartigan holding his hand on her chest. When it cuts his hand is on her back. (00:34:40)
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 Right then you'll notice that Elora's been replaced by an obvious doll.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: 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)
Continuity mistake: During the wagon chase when Madmartigan is going head on head with the other wagon he throws his weapon right at the warrior holding a spear. When he hits him his spear is visible but when it cuts to him actually falling off the wagon the spear has disappeared. (00:51:05)
Continuity mistake: When Madmartigan comes rolling down as a huge snowball and hits the wall, snow splatter through the window and hits Willow's head making his hair wet. But a few seconds later when Willow comes out of the hut his hair is dry. (01:13:20)
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mistake: When Madmartigan and Willow are about to crash against a rock and when they're speeding downhill, Mad's been replaced by an obvious stunt holding an ugly doll.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)
Continuity mistake: When General Kael takes the baby to Nockmaar Castle, it has an extra 'turret' on the left-hand side, which has disappeared when Willow and Fin Raziel face the castle later on. (01:31:40 - 01:41:15)
Revealing mistake: Madmartigan kicks a baddie but his foot misses by far, despite the thump being heard. (01:31:44)
Continuity mistake: Before Airk is killed, Madmartigan stares at the fight with his hair soaking wet and messed up. When he runs to talk to Airk, ten seconds later, his hair is nicely brushed backwards. (01:52:24)
Continuity mistake: When Bavmorda is choking Fin, Fin reaches for her neck, but a shot later her right hand is grabbing Bavmorda's hand. (01:54:03)
Continuity mistake: After Fin is almost killed, Bavmorda and Willow talk, the way the blanket folds over his hand and the amount of loose blanket on the right differs noticeably between shots. (01:56:53)
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!).
Continuity mistake: Near the end of the movie the camera pans to different villagers as they notice Willow returning after his journey. One of the villagers they show is Willow's wife, although they show her in another scene (a minute or so later) walking from a different area and noticing Willow for the first time (again).
Suggested correction: The first woman we see at 1:59:40 looks like Kaiya but her hair is long (while Kaiya's hair is a short bob), and she wears a long brown dress while Kaiya (at 2:00:15) wears a midcalf reddish-brown dress with a white apron.
Continuity mistake: When Madmartigan hands Willow a sword in the castle, then pulls his own sword, it has blood on it but as he jumps on the 3 headed monster, you can see a clean shiny sword (no more blood on it).
