The rule of thirds is a method used in the film industry where each shot can be pictured as a three by three grid. At each of the four points these are seen as the attention points of audiences when watching a film, therefore it is important directors and producers ensure they are abiding these rules.

As established in the diegetic and non-diegetic sound analysis, film crews often hire or use someone called a 'foley sounds artist'. Foley artists concentrate on sound effects in films, recreating representations of real life sounds in a studio to later be layered over to emphasis the 'real' stereotypical sound. One prime example of this would be when a protagonist is wearing chainmail amour. A foley artist will replace the default SFX with a recreated sound, using items such as large bike chains being rattled to establish the armour.
