'Unbreakable' Final Scene
The use of sound in a movie is very important as it helps tell a story and manipulates the audience's emotions when watching. Within a thriller film the sound helps build tension and suspense in order to make the audience feel anxious and on-edge.
This scene is full of non-diegetic sounds. The sound made when the antagonist and the protagonist shake hands is non-diegetic and also contrapuntal as you would not expect this sound when characters shake hands. The sound that is used when the characters shake hands is very affective as it portrays the strength and importance of the protagonist's vision. This sound effect is conventional to a thriller as it shocks the audience and twists their opinion on the antagonist, leaving them on the edge of their seats to continue watching. This idea of hooking the audience through shock and grabbing there full attention is the purpose of a thriller film.
During the protagonist's vision you hear an explosion. This is an off-screen sound as you can't see where it has come from, and it is also a diegetic sound because the other characters can hear it. You can also hear the other characters reacting to the explosion and mentioning a train. The audience immediately realises that the protagonist's vision is referring to the train crash that occurred at the beginning of the movie. Loud diegetic sounds (such as explosions) are conventional to a thriller film as they display a chaotic atmosphere to the audience which puts them in the mindset of the character and leaves them feeling an intense excitement.
The music that is played after the vision is non-diegetic as the characters cannot hear it. The music is dark and atonal which portrays the tense atmosphere of the scene. This style of music is conventional to a thriller film as it builds suspense within a scene and makes the audience feel anxious. Music which explores different extremes in dynamics, pitch and tonality is expected when watching a thriller film as it portrays the emotions of the characters and makes the audience feel on-edge.
Another non-diegetic sound that is used is the protagonist's heavy breathing. This is non-diegetic as the character is not literally breathing that heavy, but it is used to portray the protagonist's erratic state of mind. The character's breathing is most probably diegetic, but because the volume of it has been increased so much it becomes non-diegetic. Sounds such as this are conventional to a thriller film as they demonstrate the character's emotions and influences the audience feel the same - making them want to continue watching.
The use of these sounds create understanding and meaning to the scene and help develop an intense atmosphere in order to fulfill a thriller genre. They also create a response from the audience and puts them in the mindset of the characters.
