There is no evidence that this experiment is really done. It seems to be so, but it is not so important. The video report afterwards is the most important part, acted or not.
The experiment is done by States United to Prevent Gun Violence (SUPGV), a gun violence prevention organization from USA. They took the glorification of the countries gun culture as starting point in a specially made film. The moviegoers expected a gun filled blockbuster. But the movie was way different from what people were expecting.
