Sound.

In our opening sequence the first 3 shots will have no non diegetic music or sounds, it will includes simply background music identical to that of what you'd expect to hear in a college (people walking,people chatting,doors opening and closing etc)

In the fourth shot this will all be interrupted by his phone ringing mid shot, his ringtone will be 'living on a prayer' by Bon Jovi to help introduce his obsession with the band. If we can't use this due to copyright, we will use a random heavy metal style ringtone to make sure it still has a strong association with his personality.

This continues throughout the next 11 shots, until he finally answers the call.

During these 11 shots, the diegetic sound will continue. But will include the first sections of dialogue, coming from the four groups who are shouting at him to answer his phone.

At the point when he finally answers his phone the focus point is on his voice and his sisters(who is on the other end of the phone)

As this cuts away,and leaves only the title on the notice board fading into the main title, The first and only use of non-diegetic music in the opening sequence will be used here. It will be a repetition of the 'heavy metal' based ringtone but clearer and at a louder volume as it's no longer drowned out by the noise from the other diegetic sounds surrounding the scene.
