1) The seduction is used to tempt audiences and keep their attention. It could either slowly introduce drama and keep the suspense rising or could have continuous drama. If it were to be full of action and drama, it would need to begin from the start of the movie. Also, there needs to be an instant impact, with lots of drama so people watch the whole of the movie and not keep them bored.
Thomas Sutcliffe: "Films need to seduce their audience into long term commitment. While there are many types of seduction, the temptation to go for instant arousal is almost irresistible."
2) The risks of 'instant arousal' mainly involve answering the questions in the mind of the viewers. The problem is that they are sometimes never answered and then it is asked what comes next. The audience may expect more drama if all of the action is crammed into the first part of the movie, therefore it is wiser to start slowly and have the drama later on, so that the audience can feel a sense of satisfaction.
3) Audiences hope to have their moneys worth. A deal must be struck to draw the rules of engagement. A good beginning would include making a judgement of how much information is given in the opening. You don't want them to walk away from the film, feeling that they know what will happen in the rest of the movie or leaving them confused. You must set enough information to foreshadow the future events, only making rules on how much you give away.
4) Kauffmann describes 'the classic opening' as an establishing shot of a place, e.g new york city (cityscape), close up of a building, then the camera window in the room to the private office and meet the receptionist and finally the important character at the desk can be seen. This makes it rational and establishes normality. This includes a normal person in the building and is in an everyday routine, but then afterwards it changes to the dramatic plot which contrasts the normality. The point of this opening to make it clear of location and introduces the characters on set.
5) The title sequence to tee film 'Se7en' creates a first impression that wakes everyone up to whats going to happen. It tells a story and foreshadows things that were going to happen. It is suggested that the opening is more influential than the film itself. It introduces us to the main character who is psychotic and has an obsessive nature.
6) He wanted to make people forget they are watching the film, without any titles, no editing, no cuts whatsoever, and use the fluidity of the camera. However universal studios made titles for it.7) 'A favourite trick of Film Noir' means that the dramatic event at the end will be shown first. It will start the movie at the end so we can go back in time and watch the build up, looking ahead to see what is to come.
