In a botched attempt to turn over a semi-trailer truck with an air cannon for a chase scene, a piece of iron debris flew toward the production crew and hit assistant director Shero Rauf. Rauf broke both his legs, and it took him almost two years to walk normally again. The accident was caught on film by the crew and was published on the web after the release of the movie. He received compensation of a mere 400 euros for the injury.
