Thriller Research- The Godfather

I have researched the genre Thriller and I found a worldwide poll in which the public chose the best and worst of thriller films. I then chose to look at the opening of the top best thriller film to see what what makes a good thriller opening. The Godfather reached number one with 365,190 votes.
The opening is intreging as the screen is blacked out, then the dialogue starts with 'I believe in America' which is intense as it makes the audience want to know the impact of what he just said and it sounds like he is defending himself.
The camera shot is a close up of a man talking about his daughter and as he talking the camera is in reverse zoom, which is a simple technique but effective in making the opening tense and already the audience are sitting on the edge of there seat.
I love how the opening is so dramatic and it adds tension to the atmosphere especially the dialogue as it talks about how his daughter was assaulted by her boyfriend and his friend, the audience gets a clear image that the man is the father and you get a sense of love he loves his daughter and the hatred he has for these men who attacked his daughter, this is easily told by the emotions in his face and his voice which has sunk the audience in to the film.
As the speech reaches to the most emotional part 'she was a beautiful girl (long pause) now she will never be beautiful again' and the father begins to cry and that line and acting is so dramatic and the audience gets emotional as well, and the camera begins to zoom out and the audience can see a shadowed head resting on a hand in the left hand corner, this makes the film more dramatic as the audience wonder who the man is and why is the father telling him this and it also gives a sense of the father seeing a councillor as the men are sitting opposite from each other.
As the camera is zooming out and the man figure is becoming clearer, then the other men immediately starts with 'Why didn't you come to me first' this gets the audience really wondering who the man is and how much power does he have to be saying that he is better than the law system.
In the opening my favourite part is when the second man asks what the other man wants done and the father whispers in his ear even though the camera is in extreme zoom between the two men the main focus is the mouth to ear, they are both blacked out which adds tension, mystery and a interest in the conversation between the two men.
As the father walks away the camera is medium zoom on the second man, he looks like he is thinking but his expression is blank which makes it seem he has heard worse things.
The opening is so dramatic and I think that's what makes a brilliant thriller opening.
