Last year I wrote my first screenplay, adapting my short story Artefact Nouveau. It turned out to be only 23 minutes long, which isn't very helpful, but I did learn a lot along the way and got some useful feedback from others who know more about the subject than I do.
This week I've started writing a new screenplay, this time destined to be a 45 minute long TV drama pilot. With this script I have much more idea where I'm going, and a whole TV series planned out. None of which guarantees that the screenplay will be any good, but I'm enjoying myself nonetheless.
