Textual Analysis of two films

We've been set an essay for media, our class has to do a textual analysis of two film. The two films I have chosen are quite different, I've chosen "Reefer Madness - The Movie Musical" and "Scott Pilgrim vs. The World"
These two films are very different to each other as they both are unique films genre-wise.
Both of these are based on other forms of media, "Reefer Madness - The Movie Musical" is based on a documentary shown in the late 1930's America, and "Scott Pilgrim vs. The World" is based on graphic novels.
