Lesson: Don't film robbery scenes in Angola.

From IMDB:

Police in Luanda, the capital of Angola, shot and killed two actors filming a robbery scene and wounded two others, the London Daily Telegraph reported. Director Radical Ribeiro said that he had seen the police vehicle racing toward the location scene. "Suddenly it stopped and people appeared on the back and without asking any questions they started shooting at everybody at close range. I don't know how I escaped, I was just two meters away." He said that although the actors were carrying firearms, they had no ammunition, that police had been notified of the filming, and they had received permits to film in the area.
