Lucy proposes a game of hide-and-seek, and Peter, hoping to humor her, agrees to be 'It' and starts counting up to 100. Additionally in the novel, the father of the Pevensie children is in London with their mother, but in the film, their father is fighting in the war as Lucy states to Mr.

When Lewis wrote the novel, it was the first of the series and the back-story later outlined by the subsequent books in the series did not exist. The film also hints at Professor Kirke's role in, such as the engravings on the wardrobe, when it is a simple one in the novel, and the Professor's surprise and intrigue when Peter and Susan mention Lucy's discovery in the wardrobe. He felt it was more natural that she first see the wardrobe while looking for a hiding place, rather than just chance upon it exploring the house. Adamson also changed the circumstances in which Lucy first comes into Narnia.


As the home of the Pevensies was inspired by Anna Popplewell, who actually is from Finchley. Minor details were added to the Pevensies, such as their mother's name, Helen, being the actual first name of Georgie Henley's mother.
