This is very interesting thanks for posting. Can see GBH winning best original.

You might be right.
One thing I don't know is wether they view the film and make a judgement, or judge the actual screenplay.

Interesting, It might be through the screenplays alone as actually viewing introduces a whole set of other factors which could influence the decision. But yeah, haven't got a clue.
