Congratulations to all the Nicholl Quarterfinalists!
The Nicholl Fellowships in Screenwriting contest is the best contest to enter in terms of getting you moved along in your career. Making any of the final rounds will garner reads and help you land representation even when you're out in the wild.
Being that it is so head and shoulders above the other contests I cannot recommend strongly enough entering early and often. Not just because it's good -- but also because your window for entry is rather narrow.
You stop being eligible to enter the contest after you've made $5,000 for writing, even if that's just from a screenplay option or optioning a book you wrote. And that's a really easy number to hit fast.
I did not realize this and only entered once before I became ineligible -- and I can tell you that I've definitely regretted it over the last couple years.
