 Halfway through this film, when Theo is walking down the ramp on  Battersea Power Station, a stenciled image can be seen on a wall of  two policemen kissing. This image was created by "Banksy", a British  "guerilla artist" who specializes in this type of work. There are  also other works of this artist in the film. One of them is a  stenciled image of a child looking down a shop.
