I try and read several other writing blogs. I saw this post earlier in the week:
While the author is not a screenwriter, her pitch to a publisher is very similar to what screenwriters do when they send a query letter to a producer or director. She breaks down her query letter and most of her comments apply to writing a screenplay query letter, too.
If you haven’t already read it, I highly recommend it. Writing a great query letter is essential to getting your screenplay read, optioned, and produced.
If you haven’t read my post on how to write a screenplay query letter, you should check out, too, How to write a professional query letter for your screenplay.
