If you are an aspiring screenwriter then you should be reading the trades. At least one of them. Personally, I prefer Variety. Sure, I know that the trades are pretty expensive for a subscription. But you can get the gist of the things that you need to know about from checking their website daily. And that is totally free.
If you are not reading the trades, I suggest it is something that you start doing. Why? Because if you are not reading the trades then you missed the story on how Hollywood is in hot pursuit of new scripts in Variety. Do yourself a favor and check it out now. Seriously.
