The T-Shirt test

You have a film idea? Of course you do.
Good characters? Obviously.
Cracking dialogue? You bet!
A film that people would want to tell their mates to go and see because its so funky? That must be a rhetorical question. Yes.

Try this 'on for size' then. Would people wear your t-shirt? Is it that good? What would your t-shirt say? Would it capture the moment?
