Less than 10 years ago Following's budget was equivalent at the amount of money that the entire production of The Dark Knight spent in napkins ($ 7,000) that's 0,003 % of the new Batman entire budget of $ 185 millions.
Guerrilla filmmakers, there's hope! You just have to do something similar to Following, a Guerrilla Masterpiece.
The Film was written and planned to be as inexpensive to produce as possible, but Nolan has described the production of Following as "extreme", even for a no-budget shoot. With no money, limited equipment, and a cast and crew who were all in full-time employment on weekdays, the shoot took a full year to complete. The production was so small that on many of the shoots, the cast, crew and their equipment could travel to their locations in a single London taxi.
To conserve expensive film stock, every scene in the film was rehearsed extensively to ensure that the first or second take could be used in the final edit. For the most part, Nolan filmed using non professional lighting equipment, employing only available light. He also used the homes and apartments of his friends and family as locations.
A struggling young writer takes to following strangers around the streets of London ostensibly to find inspiration for his new novel. Initially, he sets strict rules for himself regarding whom he should follow and for how long, but quickly discards them as he becomes addicted.
