The ad ends with the youngster - who finds a clumsily-wrapped night light under the tree on Christmas morning - being reunited with the sounds of his friend once again when he switches it off.
The department store drafted in Oscar-winning film director Michael Gondry to work on the two-minute ad, which sees John Lewis return to its tear-jerking formula after a more humorous turn previous year by Buster the bouncing Boxer dog. Michel Gondry directed the ad. ICYMI, he also directed projects such as Eternal Sunshine of the Spotless Mind and Daft Punk's "Around the World" music video.
Michel Gondry added: "When I told my ex-girlfriend I was doing the next John Lewis Christmas film, she said, 'You have big shoes to fill, this John Lewis commercial must make people cry, don't forget.' Last week I showed it to her and she cried".
And sure enough, the folks at MyVoucherCodes have risen to the challenge of emulating Moz The Monster's under-the-bed antics, having delivered a micro-budget remake of the ad.
Craig Inglis, customer director at John Lewis, said: "This year's Christmas campaign brings to life the power of children's imaginations and the joy of great friendships".
This Christmas John Lewis has chosen Barnardo's as its charity partner and will make a donation to the charity from the sales of Moz cuddly toys and mugs.
Over the past few years, John Lewis has celebrated Christmas through gift-giving and love receiving. The advert will first be shown on TV on Friday 10th November at around 9.30pm on Channel 4 - during Gogglebox.
To standard I think, rather than setting a new one.
