Visible crew/equipment: When Mrs. MacReady meets the Pevensie children at the train station, the reflector screen is reflected in the lenses of her glasses, as she looks down when she speaks to them. It is also visible when the children first arrive at the house, when Mrs. MacReady says, "There shall be no disturbing of the professor." (00:07:30)
Continuity mistake: When Edmund speaks with the White Witch the first time, as he eats the Turkish Delight candy, the amount and pattern of powdered sugar that remains on his lips differs in the following shots, depending on camera angle. (00:31:10)
Continuity mistake: When Peter finds the note about the capture of Mr. Tumnus he pulls it down off the nail, ripping the top edge of the paper. In a following shot the top edge of the paper can be seen fully intact, then ripped again. (00:41:20)
Continuity mistake: After falling through the wardrobe the first time, when Lucy places her hands on the snow covered lamppost, she leaves marks on it which repeatedly change in the following shots. (00:13:50)
Continuity mistake: When Lucy is at the lamppost the first time, in one shot she has her right hand on the post, in the next overhead shot, her left hand is on the post. The next shot, her right hand is back on the post. There is no time for her to switch hands. (00:13:35)
Continuity mistake: When Mr. Tumnus meets Lucy, the amount of snow on his umbrella differs. (00:14:40)
Audio problem: When they're standing on the breaking ice, as Peter points his sword at Maugrim, Susan shouts, "Look, just because some man in a red coat hands you a sword doesn't make you a hero. Just drop it." In the very next shot (we still see Susan's profile, despite the side shot), Susan's lips/jaw are moving, but nothing is heard, which occurs just as Peter quickly glances at her and we also hear Beaver shout, "No, Peter!" (01:14:15)
Continuity mistake: When the four children are waiting for Mrs. Macready to pick them up, a car drives by leaving tire tracks in the dirt road. When the horse drawn cart comes up the road towards them, the car tracks have vanished. (00:07:10)
Continuity mistake: When Susan shoots the arrow into the target, in following shots the arrow's position differs. (01:27:25)
Deliberate mistake: Obviously due to the family nature of the film, but when Peter stabs the White Witch's henchmen at battle, the sword always remains clean, and never bloody. (This is a Disney family film and as such no blood is shown. Still a mistake, but there's the reason). (01:56:10)
Continuity mistake: When the train is pulling away from the station, the Penvesie children are leaning out a door window waving, and the small compartment window next to them is open, with hands sticking out, waving goodbye. In the following shot no hands are sticking out the window. (00:05:00)
Continuity mistake: When Edmund is eating the turkish delight, the shape/size of the pieces he eats differ, due to the bites changing between shots. (00:31:10)
Revealing mistake: When the girls are on Aslan's back, you can tell that there is a flat screen behind them.
Revealing mistake: Aslan is carrying Lucy and Susan on his back to the battle and is running at a very fast speed. If you look at the girls' hair though, it isn't moving at all, flat against their backs as if there wasn't any wind. (01:51:20)
Revealing mistake: When the Beavers and the Penvesies trek along the ice river, the Beavers drag their tails along through the snow, yet the snow is never disturbed by them. (01:03:35)
Revealing mistake: During the battle scene, the White Witch clearly stabs Peter in the arm with her sword. In the very next shot the sword goes through the chainmail behind his arm, into the ground. (02:02:40)
Continuity mistake: When Lucy and Mr. Tumnus first meet, he drops his packages on the snow covered ground. The positions of the parcels are quite different in the overhead shot, as Lucy walks over to Mr. Tumnus. (00:14:00)
Continuity mistake: When Edmund is talking to Peter after they've found out that Aslan has died, Edmund has a cut on his lip for most of his close-up shots. But after Edmund says, "Aslan believed you could and so do I," in his next close-up shot, the cut on his lip has disappeared, but it reappears later.
Continuity mistake: When Edmund first enters Narnia, he falls backwards out of the last of the coats and onto the snow. There is a close-up shot of Edmund as he lands on his back, and we can see a sprinkling of snow already on the front of his robe. In the next shot, he sits up, and the front of his robe is immaculate. (00:27:20)
Visible crew/equipment: When Lucy, Peter, and Susan are riding on the ice chunk down the river, when you see a shot of Lucy struggling to maintain her grip on the ice block, immediately after, there is a shot of Peter holding what was supposed to be Lucy. However, it is not Lucy. The person Peter is holding is bigger than Lucy and had blonde-brown hair.
