Other mistake: There is scene in which the assassin is mocking the young would-be suicide bomber and his friend for eating with knives and forks whilst he eats using his hand to pick up the food. However, he eats with his left hand which is absolutely forbidden under Islam. All Muslims eat with their right hands unless they are unable to eat with it (for example if they have a broken arm).
