If you look closely you can see members of the band in the background as well as the crew from other music videos. Director of 'Feels so Right' Eunji Kim is seen behind the boy as well as producer Joanna Bence, production manager Zee Faloon, art director of 'Gain Control' Adriana Paramo Perez and the 1st AD of 'Codeine and Wine' Giannina LaSalvia.
In order to get extras the crew hosted a party at the location, offering free beer. This was meant to be drunk after the shoot had finished but did not go according to plan.
The projection of the girl was shot a week before the shoot, before the part of the boy had even been cast. They never met.
David Lyon did 4 takes of jumping out the window. In the last take he hooked a row of fairy lights on his foot and brought them down with him. The director liked it so much he left it in the film.
