Watch the precious Christmas advert that's melting people's hearts

John Lewis' new Christmas advert has left viewers in tears over a mischievous and flatulent monster called Moz and his relationship with a seven-year-old soulmate - with fans comparing it to Disney's much-loved Monsters Inc.

The giant furry monster with a bulbous nose, wonky teeth and a love of snoring, jumps out from under the bed every night to play with companion Joe in a festive tale making many laugh and cry.

The little boy, aged 7, who is played by young twin brothers from London named Ethan and Tobias, is initially frightened after seeing a pair of enormous eyes peering from the dark under his bed, the Daily Mail reports.

But the two unlikely friends are shown sharing games, playing piggyback and Scalextric in his bedroom – all without mum, dad, or older sister finding out.

Moz then leaves his friend as he realises the little boy needs to grow up without him and wraps a farewell gift for him under the Christmas tree - a nightlight to help him sleep.

Viewers have compared it to Monsters Inc, especially because Moz has a sock stuck to his fur - known as a "23/19 violation" in the Disney movie where characters sneak into bedrooms to make children scream.
