Placing in a well respected screenwriting contest can bring your writing to the attention of the industry. Here’s my round-up of the best film and television writing contests in the UK and US.
Script Angel is a fantastic resource, and one you should really take advantage of.
Last October I won a screenwriting competition that I found through her blog, and I am still ridiculously grateful to her.
Make sure your screenplay is as good as possible before entering - there's no need to rush. These competitions run year after year and you want to give yourself the best chance possible. Don't enter without getting as much feedback as possible from those around you, and don't forget to check for simple things like typos.
Basically, make sure it really is the best it can be before you start forking out the cash for the submission fees!
