Continuity: When Edmund is rescued he has a big cut on his lip. When Queen Jadis and Aslan go into the tent for their meeting it is a smaller cut, and when they come out it is bigger again.
Incorrectly regarded as goofs: Near the end of the movie, Lucy gives Edmund the potion that is able to heal any wound. His major injuries are healed, but the cuts on his lip and face remain. When Santa gave Lucy the potion, he told her that putting the potion on any wound would heal it. When she gave the potion to Edmund she gave it orally, so it would heal his internal wounds.
Continuity: When Lucy first arrives in Narnia, and sees the lamp post. She touches it with one hand, but when she hears Mr. Tumnus coming, she's touching the post with the other hand.
Continuity: In the opening scene when the Germans are bombing London, the shot of the sky shows that it is very cloudy. However, when Peter and Edmund are running after retrieving the photo, the planes are clearly visible and are not masked by any clouds.
Continuity: When Edmund meets the White Witch, her servant forces Edmund onto the ground. He has snow in his ear. In the next shot it is gone, then it comes back again. When he stands up, the snow is gone again.
Continuity: In the final battle with the Witch, Jadis first stabs Peter through the middle of his sword arm and the grass is green. When the shot is cut back to Peter and Jadis, the sword is only going through the chain mail on the upper part of his arm and the grass is brown.
Anachronisms: The coaches of the train on which the Pevensie children travel have Great Western Railway colors and lettering. The engine, No. 7802 Bradley Manor, is painted and lettered for British Railways, which did not form until 1948, after the war ended.
Continuity: When Lucy is talking to Tumnus after entering Narnia for the first time, she touches the lamp post which is covered by snow. Her fingerprints in the post change positions many times.
Continuity: When Lucy opens the wardrobe for the first time, three moth balls fall out. The camera backs off and you see all three of the moth balls stop in plain sight. Lucy turns around and then steps into the wardrobe. When the camera backs off again (showing Lucy closing the wardrobe door) the moth balls are gone.
Continuity: Peter's label changes position during the back and forth while talking with Mrs. Macready.
Continuity: When entering Narnia, Susan has a hairpin in her hair on the right side of her head. A few shots later the hairpin is gone.
Continuity: When the kids meet Mr. Beaver, Peter and Susan are holding hands on Peter's arm. In the next shot, they let go but in the shot after that, they are holding hands on his arm again.
Continuity: The position of Mr. Tumnus's dropped packages on the ground.
Continuity: When Lucy first enters Narnia and meets Mr. Tumnus she hides behind the lamp. When she comes out from behind it she has snow up the front of her dress to her waist, in the next shot she only has snow at the hem of her dress.
Continuity: When Edmund first enters Narnia and falls on the ground, his hair is flared out when he is lying in the snow, but perfect in the next shot as he begins to stand up.
Continuity: When Edmund is eating Turkish Delights after meeting the White Witch, the food changes hands (right-left-right) several times, and the powdered sugar on his clothing and mouth change position between shots.
Continuity: When the children are running around in the house trying to find a hiding place while playing hide and seek, Lucy's dress changes from purple to brown.
Continuity: When Peter is fighting the Witch and turns around to see Aslan, he has a cut on his right side of his face, above his eye. The blood had run down past his eye. When Lucy heals Edmund the blood trickle is smaller.
Continuity: When Lucy pulls back the tree branches to enter Narnia for the first time, her hair is curled inward. When she feels the snow and looks around, her hair is curled outward. Then when she looks up, it is inward again.
Continuity: When Susan, Lucy and Peter find Edmund lying on the ground (after the battle), Susan is sitting to the side to Edmund's head and proceeds to take off his helmet. In the next shot, Edmund's head is resting on Susan's knee.
Continuity: When the Pevensie children are playing cricket, the ball hits Edmund and bounces to his right. A second later Susan picks it up from behind him and to his left.
Revealing mistakes: Peter's sword can be seen bending multiple times throughout the movie as though it was made of aluminum or rubber.
Continuity: After the fox has just been turned to stone, The White Witch slaps Edmund on the right side of his face, but later on in the film, he has a bruise on his left side and nothing on his right.
Continuity: During the coronation scene after they have all been crowned they sit down on their thrones. Afterwards there is a zoom in on all of their faces, but when they zoom in on Peter's face he is clearly still standing in front of his throne not sitting in it.
Continuity: When entering the camp there are two long shots of the three, in the first shot Susan has knee socks on, in the second of the shots it looks as if she had no knee socks.
Continuity: Toward the film's end, when Peter, Susan, Edmund and Lucy walk alongside Aslan toward the end of the film in order to be crowned, there is a brief side shot where someone other than William Moseley is playing Peter.
Continuity: When Lucy, Peter, Susan and the Beavers are just coming out of the tunnel, just before Lucy falls, her coat is on, then when she falls and they have a close up of her, her coat is off. When she is walking with Peter and Susan her coat is back on again.
Factual errors: In the beginning, when the German airplanes are bombing London and Edmund and Peter are in the garden in front of their house, you can see the shadows of the airplanes on the ground. This is not possible because it is night and there is no light above the airplanes that could cause those shadows. On the contrary, searchlights tried to discover those airplanes from below pointing into the sky. If there was a light above the airplanes strong enough to create shadows, they would be moving much faster.
Continuity: When Susan goes to practice her bow Lucy joins her. Lucy then throws her knife at the target and hits the bullseye dead on. When the camera pans back to Lucy with a big grin on her face you can see her knife tucked safely away in its sheath.
Revealing mistakes: When Aslan jumps at the White Witch just before she can kill Peter, the Witch can be seen starting to fly backwards as if struck before Aslan's front paws actually touch her.
Revealing mistakes: In the railway station, the train is stationary in several shots when it is supposed to be moving. The doors are alternately open and closed in these same shots. In some shots, the train's billowing smoke column disappears entirely. At one point just before the children get on (and we see the caption: directed by Andrew Adamson), the train simply vanishes for a short time during the shot overlooking the station.
Continuity: During the coronation, Mr. Tumnus places a crown on Lucy's head. The front of the crown rests about 1 inch from her hairline. (Where her hair meets her forehead.) As the shots go back and forth between Lucy and Tumnus the crown gets closer to the hairline, resting just above her forehead and back again.
Continuity: 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.
Revealing mistakes: When Susan and Lucy are riding on Aslan's back to the castle, he is traveling at a great speed, but they are sitting upright and their hair is hanging down as if they were sitting still.
Incorrectly regarded as goofs: Several times cheetahs and leopards can be heard snarling like mountain lions, but this is no more incredible than lions and gryphons speaking English.
Continuity: When Edmund follows Lucy into the wardrobe, Lucy closes the door to the wardrobe, then as Edmund walks into the room the door is shown slightly open, then it is closed again when he goes to open it.
Continuity: At the beginning of the movie and all throughout Lucy's hair is red. Near the middle of the movie her hair starts getting progressively darker, especially after meeting Aslan at the camp. When she is crowned her hair is completely dark. When they show the older version of her she has red hair and when she falls out of the wardrobe she has red hair. It stays red for the rest of the movie.
Crew or equipment visible: During the final battle, when one of the centaurs charges the Queen's soldiers, one of the animal soldiers attacks him. When he kills the soldier, a harness is clearly visible as it hoists the soldier up in the air as he falls to the ground.
Revealing mistakes: When Tumnus walks Lucy through the snow to his home, Tumnus should be leaving hoof prints, but leaves James McAvoy's boot prints instead.
Continuity: At the beginning of the battle, Jadis appears from behind the hill with all her troops, stopping close to an upper natural "step" in front of her. Later, she orders her bears to move, but we don't see her falling - the step is gone.
Errors made by characters (possibly deliberate errors by the filmmakers): The Pevensies observe blackout rules poorly. They have no blast tape on the windows, no blackout curtains, they open their curtains with the lights on, they leave lights on while they open the back door, etc. Then they are still in the house while the planes are going over. The war sirens went off when planes were spotted a couple of miles from the city itself, so the family should have had plenty of time to get out the house into the air raid shelter. Even though moments of terror make it hard to observe rules, it was precisely this terror that made Londoners obey the rules so strictly.
Audio/visual unsynchronized: When Lucy closes the spare room door, the sound is of a modern tube latch striking a faceplate. But the door shown has an old-fashioned cupboard latch, which would sound different when closing.
Incorrectly regarded as goofs: When Peter, Susan and Lucy first arrive in camp, the head centaur is blackish dark brown. In later scenes he is chestnut light brown. This could be part of his natural cycle, as some real-life mammal species change color in different seasons.
Errors made by characters (possibly deliberate errors by the filmmakers): Near the end, Professor Kirke says that one can get into Narnia is only when not looking for it. This was already disproved by Lucy's second entry into the wardrobe, when she went there with Narnia in mind. Every other time the lore holds true.
