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" this means films should get the audience interested straight in, by using action!
According to the director Jean Jaques Beineix, the risk of "instant arousal" is that if you get the audiences straight into action in the film, the excitement would leave the audience satisfied and they would expect to see more action after, so its more better to start with a steady calm begining and then go straight in with the action.
"a good beginning must make the audience fel that it doesn't know nearly enough yet, and at the same time make sure that it doesn't know too little" this is successful because if the audience know too much already in the beginning, there is not interesting moments after because they already know whats expected, and if the audience know too little they would loose interest by not not knowing much about the film.
the critic Stanely Kauffmann describes as a a classic opening is, a shot of a city scape, then a zoom up of the building then a shot of the window and then you go through the window straight into the building, this works because creates a mood depending on the music and the setting of where the place is.
