Final concept

We would begin filming in central London, firstly with the man walking up from the underground. He seems all confused as though he has never seen anything like this.

We would show London through his point of view so he would look around the city. This would be to emphasise the hustle and bustle of london. 

At 0:18 he would then put the headphone on an begin to walk through the city. 

We then thought that something strange could go on behind him while he has his headphone on, and then when he takes his headphones of it all stops. For example people dancing behind him.
A shot of him almost falling into a taxi and sitting in the taxi. However we would then show the drive through his point of view.
