I saw this film poster in downtown Algiers in December 2013, and I thought there was a grammatical mistake. I approached a person at the entrance of the movie theater and I asked him about the mistake.
"Do you think the producer would have allowed such a mistake?" he said.
"Maybe not," I answered.
So the grammatical error in the title is not an error because the sentence was found written on the door in the house where an old lady was murdered in 1991.
Omar was the old lady's gardener, and the sentence was enough to convict him of the murder and sentenced for 18 years in 1994.
The movie is about racism as much as ethnic profiling in the West. It is about the murder of a rich widow, and whom else can be accused but her gardener who is a immigrant from Morocco.
