Firstly, if you want to score well in an AOS essay, choose sophisticated texts; if you choose a childish and crappy text like Harold and Kumar, it will not reflect anything good about yourself towards the marker's impressions. Choose good films, dramas are preferred.
Secondly, use the word FILM, not the world movie, I know you can class Harold and Kumar as a movie because it is pop culture but use the word FILM when you realise that you should analyse a more serious text.
