Continuity mistake: In one of the major battles, Wallace is charging down a hill with a large sword in his hand. During the charging it changes to being a small pick axe type tool. Then around the middle of the charge there is a quick shot change and almost from the same angle the pick axe has disappeared. It then changes back to a large sword, a quick change back to the pick axe, then back to the large sword. (01:28:20)
Continuity mistake: In the first large battle with England at Falkirk the same scenes are used when the English fire the arrows. The first time the arrows are fired, a blonde young man is hit in the foot, they then moon the English so they fire again and the same man is seen getting hit in the same foot. A man in the same battle is shot in the hip - when he grabs the wound you can see the shape of the cushioned bulb that the arrow is attached to. If you watch during all the battle scenes you can detect men who are supposed to be on opposite sides standing and talking, also you can see the choreographed moves being played out in almost slow motion - their swords aren't even striking.
Continuity mistake: When Wallace tries to escape from the English with his wife, not knowing that she has been captured and executed, he is seen running through the woods screaming her name... As he's running he has a sword in his right hand. During the course of three or four camera shots, the sword he is holding magically disappears and reappears as different cameras shoot him. Then it reappears and he digs it into the ground as he takes off the English soldier's uniform that he stole. (00:42:35)
Continuity mistake: When William comes to take Murron on a horse ride in the rain, he talks to Murron's parents. The camera cuts to Murron a couple of times, ducking under the shelter, and her hair is completely dry. But when she rushes out and jumps onto William's horse, her hair is soaked. Obviously this scene took several takes, and they didn't take the time to dry the actress's hair between each take.
Continuity mistake: During the scene in which William Wallace is being executed, the camera pans the crowd and shows the ragged peasants staring in silence. An extra, who is a young woman with light hair and a dirty face and is standing near the front of the shot, stares directly at the camera for a few seconds while all the other extras look in a different direction towards the execution. (02:44:00)
Continuity mistake: Just before Wallace picks up the archer to throw him over the ledge, you can the archer has a tin looking hat around his head with part of his suit covering his head below the hat. In the shot from in front of the ledge when Wallace is throwing him off the cap has now disappeared before he has been thrown. The following shot as he is falling its a bit hard to see his cap but you see it come off. (00:50:45)Lummie
Continuity mistake: In the scene where William Wallace charges after the king's brigade after the Battle of Falkirk, and Robert the Bruce (disguised) turns and charges at him with a lance, Robert is wearing two distinctly different silver helmets before he hits Wallace and after. These two helmets are seen interchangeably in the preceding scenes also. (02:02:00)coldteeth
Continuity mistake: When Wallace arrives at the home of Murron to invite her for a ride in the rain, the mother's head covering changes several times between shots. Sometimes it has the yellow fringe close to her face and other times it does not have the fringe at all. (00:29:40)
