Through out the year i constantly changed my related texts simply because they weren't getting the marks i wanted... but non the less they were still relevant texts..Anyway
My prescribed text was - Shakespeares As you like it
My related texts i used or you could use: Donnie Darko (film), Fight club (novel and a film- film is better for technique etc), Into the wild (film), Christina Anu - my island home (song), The lady of shalott - Alfred Lord Tennyson (poem). also a short film - man kind is no island..
Look up tropfest past short films alot of those can show belonging
you should have 2 solid related texts.. anyone of these texts are good for belonging... but then again it depends on your prescribed text.. take it to your teacher and see if they can fit... probably could..
