Just a short one today...
You know what the world of screenwriting really needs? An Alan Ayckbourn.
Someone who knows cinema inside and out.
Someone who's a natural born storyteller.
Someone who experiments with the form of the medium, in surprising and exciting ways, without sacrificing character, depth, meaning, entertainment, and narrative. And with something to say about the world (in his case, male-female relationships, mainly).
Until the screenwriting Ayckbourn comes along, do yourself a favour. Read his plays. They are AMAZING. And they will spark your imagination and your desire to create.
