I've been a writer for over a decade but moved into directing. I'll be directing my first feature this year (very soon actually) which is currently in pre-production. www.intoblack.com.au for the not so subtle plug.

I have produced before (including a micro budget feature). Have to say though it's not something I enjoy as much as the writing/directing side of it, but at the lower end of filmmaking everyone has to wear multiple hats so you do the best you can with what you have.
