District B 13 (French title Banlieue 13 or B13), is a 2004 French action film, directed by Pierre Morel and written and produced by Luc Besson. The film is notable for its depiction of parkour in a number of stunt sequences that were completed without the use of wires or computer generated effects. Because of this, some film critics have drawn comparisons to the popular Thai film Ong-Bak. David Belle, regarded as the founder of parkour, plays Leïto, one of the protagonists in the film.
