When Nick Jablonka uploaded his take of John Lewis' famous Christmas advert onto the internet, he never expected it to be so popular.

The piece, called The Snowglobe, was created as part of his media A-level coursework during which he looked at company's successful marketing campaign.

Although it received full marks, Nick wasn't going to upload it to start with but then thought he had nothing to lose - it has now been viewed almost half a million times and the company has invited him behind the scenes to see how they make their adverts.

Since the video went viral, Nick has been inundated with requests for interviews, appeared on Good Morning Britain and has also been offered a job by a PR agency.

He created the video using various computer programmes and it took him about two weeks to produce. It features a snowman inside a snowglobe, and the music is Vapor feat Adaline, Follow You Follow Me.

Writing on his YouTube channel, he said he believes the piece could do with a lot of work.

He said: "It was a very rushed piece, I left it till the last month to do it. Creating a short film is a lot of work especially when it's CGI, I was responsible for things outside of my comfort zone like character animation and lighting."

Nick created the video while studying for his A-levels at Robert Napier School in Gillingham. He is now studying at Bournemouth University.

Headteacher Andrew Minchin said Nick always had a talent for computer software, engineering and design.

He said: "He has always been very creative and had a high profile around the school. His videos have the wow factor, they're incredibly creative. It was sort of expected. Some of the stuff we saw last year was really astounding.

While at the school, Nick created videos for open evenings and was also deputy head boy.

Mr Minchin added: "He really is a role model for all the students at the school. He's someone from Gillingham that can go out and really take on the world, he had those skills."

Mr Minchin said he is sure Nick will be visiting the school in the future.

A John Lewis spokesperson said: "Nick is clearly very talented, and we'd love to invite him in to spend some time with us behind the scenes to see how we create our TV ads."
