Rule 3: Reality it aint
Rule 3 says : Your script is not reality and you should avoid your characters mentioning other films.
Here's the problem, you are watching a film and in the film they mention another film that you've seen. Where should the line of reality be drawn, should we assume that the characters in the film have seen that film and therefore other films? But, there must be other films these characters have seen except perhaps those films that their co-stars act in - because how could they see those - their co-stars would have to be celebrities in the film you're watching.. brain melting...universe imploding.... head hurts!
It's irksome, annoying and totally illogical that characters in one piece of fiction would have watched one other piece of fiction. To an audience it's really jarring. It's like the stars of Coronation Street (UK Soap opera) sitting down in an episode to watch Eastenders (a rival UK soap).
An audience can accept the world of the film but as it starts to eat into our reality we question the universe's logic (more on Universe Logic later).
My favourite example is the coffee maker advert starring George Clooney and John Malkovich as God. In the advert George appears to play himself, he goes to a store buys a coffee maker and then get squished by a piano. He arrives in heaven and tells god he's not ready can he be sent back. God sends him back in exchange for the coffee maker.
Hold on! Wait a moment! God is John Malkovich and George is himself.. how can that be.. doesn't George recognise his co-star of 'Burn After Reading'? What universe are we in where one actor exists but the other doesn't?
Okay maybe I'm taking adverts too seriously.
In conclusion : If your characters watch films, make them up (like Purple Rose of Cairo).
