Intertextuality

Intertextuality is the relationship between texts it is where a text references another text

          here are some of interxtuality in films :
In Shrek they reference snow white and the seven dwarfs.This provides humour in the film and makes it relatable as most people have been read snow white and the seven dwarfs to when they were young,Therefore the old and the new generation would understand the reference.

 In  one of the episodes of Simpson they references the silence of the lambs made in 1991.This is aimed at a slightly older audience who would be familiar with 90's films.

 Shrek opens with a fairy tail book that references a classic tail of sleeping beauty.The version of sleeping beauty fairy tale in Shrek has a twist, this adds humour.

Those examples show that many references are used in films for the effect of humour or for the satisfaction of recognition of the audience.The way in which those references are interpreted  depens on the audiences kowledge of other texts.Therefore it is the audience is the one that creates meaning .
