Intertextuality

Today I researched into a few more theories and came across Julia Kristeva's idea of Intertextuality. She states it is "any text that is the absorption and transformation of another!. I began looking for examples of intertextuality in media texts and found that it is very common for media texts to be influenced by eachother.
For example:
Avril Lavinge's music video 'Alice' is a direct link the novel "Alice in Wonderland" as well as the 2010 film.
