Soundtrack Analysis of 28 Weeks Later

For 28 Weeks Later

No usage of non-diegetic sounds, mostly diegetic sounds such as the character(s) narrating what has happened and creaking of doors throughout the first 40 or so seconds to establish and focus on backstory.

More usage of diegetic sounds when the first character gets infected and screams leading to a sense of panic amongst both the characters and the audience. 

The first  time non-diegetic sounds are utilised after that scene including atmospheric, quick, abrupt music to add an element of thrill and draw attention to the fast-paced action scenes.

Music gets louder by every minute and is especially amplified in the chasing scene which sees a main character running away from a horde of zombies after leaving his family behind, this is likely to represent the mixture of difficult internal obstacles he is facing such as his guilt and grief for losing his family and the panic of having to survive.
