John Lewis advert

I keep seeing the John Lewis 'Never Knowingly Undersold' advert on the television and I absolutely love it.
From an inexperienced media student, I'm really eager to learn how the split screen is done - and how it is made to look so effortless.The music is brilliant as well - a new artist like Paloma Faith singing an old song really fits with the theme of the advert; new and old.
Also, as a sucker for anything romantic, I really like the portrayal of the love story between the two characters who are in different time periods. The subliminal message that the things that are important never change is lovely.

Who knew it was possible to like an advert so much?
