The French and guns
At 1:20 in the trailer she is firing an obviously unloaded gun, oK. But she then points its muzzle at the friend to whom she is talking. These film makers need to take a basic NRA course and know you don't point guns at your friend at the range like that. a US firing range she would be thrown out.
By the way if a woman is raped in France and has the guy still at large, she can't get a simple five shot revolver for six months, that is the minimum time period. And she could never carry it no matter what training.In the US if you need one the maximum is some training that can be arranged in a week, background check and at most ten day wait.
