info: budget and filming time

The director said that they shot the movie in 12 days with a budget of £60,000 and that before shooting they spent 6 months doing workshops with the actors to get them into the part and make sure they knew what they were doing(most of them were not professionals, like one of the dealers, who went back to jail for dealing drugs right after they finish shooting the movie). He also said that they didn't get all the licences necessary to shoot a movie in London and that the scenes in Soho and central London were made with a cameraman following Tony around the city (Gerald also said that people in the street were quite mean to Tony and shouted insults at him).
I thought this was a nice piece of info. You don't need fake blood or a big budget to make a very sharp movie.
