Goofs

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.

Lucy got back her handkerchief from Mr. Beaver in the beginning, but it seems like Mr. Tumnus returns it to her again in the end, when they see Aslan walking away on the shore. However, it is likely that Tumnus is giving her his own handkerchief in the end, as the embroidery known to be on Lucy's is not seen.

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.

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.

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.

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.

When Tumnus walks Lucy through the snow to his home, Tumnus should be leaving hoof prints, but leaves James McAvoy's boot prints instead.

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.

When Susan, Peter, and Lucy are traveling down the river, Lucy begins to fall off the ice. Peter helps her get back on and Georgie Henley's double is seen acting as Lucy.

When Lucy reaches the upstairs hall of the house and is looking for a hiding place, she tries the first door, which is locked. The second door is unlocked and she enters the room. The problem is that the room has windows on both walls. This would be impossible if the first door really led to a room.

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.

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.

When Lucy's mother is pinning the ID to her coat,you hear her say "You warm enough?" Her lips move with it, but after Lucy nods, she says "Good girl," but you don't her her mouth move.

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.

A prophecy is said to predict future events based on preternatural knowledge.

If it is possible the prevent a prophecy from coming true then it is not a prophecy and should not be called as such. If it is not possible to change it then the White Witch's efforts to prevent it coming true are futile and everyone including her should know this.

It is implied at the end of the movie that the children have spent many years in Narnia and have grow into contented young adults.

However, in a place with no other humans apart from your siblings to interact with, this contentment would be very limited.

For example, dating, marriage, starting a family of one's own; none of these would be available to the children in Narnia.

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.

Many of the Narnian animals "speak" like different animals. The badgers make guinea pig sounds. Cheetahs, leopards, tigers and a lioness snarl like cougars.
