John Lewis' Christmas Ad Introduces 'Moz the Monster'

In previous years, retailer John Lewis has introduced a series of charming characters in its annual Christmas commercials and this year is no different, with the John Lewis Christmas ad 2017 starring 'Moz the Monster.'

The Moz the Monster ad tells the story of a boy named Joe who finds a tall, imaginary monster living under his bed. After a while, the pair becomes great friends, a relationship that actually begins to affect the young boy's sleep. For Christmas, Joe finds a present from Moz under the tree -- a nightlight that projects stars, making it possible for him to get a good night's sleep once again.

As part of its #MozTheMonster campaign, John Lewis introduced an online tool that lets users create play with and take a selfie of their own monster.
