Richard Dyer's Theory
Katie Perry's- Last Friday Night (T.G.I.F)- music video is a good example of this star theory as it not only reflects a separate version of Katie Perry as she is in real life but it also reflects the zeitgeist and ideologies of the time. She reflects the ideals of having fun and the ideas of youth at the time, which is also relatable to her fans.
Goodwin's Theory
Michael Jackson's- Thriller- is an example which aligns with this theory of what a music video is made up of. It consists of many things such as genre typical style, lyrics that link to the video and even some sorts of intertextuality with creatures such as the werewolf and zombies!
