What is intertextuality?
First, it took me ages to pronounce the word. But when I finally did, I conducted a little research and finally came up with this:
Intertextuality is when a film borrows ideas, scenes and other things like that from another movie, often made many years ago so people don't really recognise the similarities unless they're a film boffin like...not me.
So it's a fancy word for copying. Not bad.
