My idea for a thriller opening sequence

An idea which i came up with for the opening sequence of a thriller was tho have a whole family in the back of a car, with a driver in the front driving them somewhere. From the beginning i want it to be evident that the wrong man has started driving there car and they are injured and scared, squished into the back of the car. So that the audience is also unaware and kept in the suspense of who the man is, i would have some low angle shots looking up at the man, showing that he has priority but the lighting of the car is so dark that its not possible to see what he looks like. I would then switch to a shot of the family in the boot of the car, which would be a farther and two young daughters, and the father is clutching his stomach with blood on his hands and the daughters faces look petrified. The back of the car would be more lit up that the front, so you could see the faces of the people in the back. This therefore would show a clear contrast between the  good and the bad divide in the car. The dress of the man in the front of the car would be all black, maintaining the mysterious atmosphere, and he would have a phone in his hand and be talking into it in Russian. The children in the back of the car would be wearing school uniform, to resemble that up until now it was just a normal day and also that they are quite young, and the man in the back of the car would be wearing a suit as if he had just returned home from work. The outside of the car would be dark and the only other lightswould be the lights of cars and overhead lights, showing that they are maybe on a busy road or a motor way, and the car would be travelling very fast down this motor way they are in a rush. There would not be a lot of conversation in this opening scene as to not give much away, apart from some screams from the girls, and the father telling them to keep calm. The non-digetic background music would be a fast action song, in order to show the genre of the film which is an action thriller.
