There aren't different rules for new writers than there are for professional writers. The way you become a professional is to write as well (and with as much voice) as a professional. If you try to write according to the rules that apply to newbies, your screenplays will read like a newbie's screenplays.



Here's the standard learning curve for new writers:



1- There are rules?

2- Fuck the rules!

3- I guess I'd better learn the rules.

4- I understand the rules.

5- The rules aren't helpful to me anymore.

6- Fuck the rules!

7- C'mere kid, let me teach you the rules.



Lots of writers think they're at stage 6 when they're really only at stage 2. But you don't start working at a professional level of craft until you've learned all the rules and internalized what they are and why they exist ... and then can break them with clear intention rather than out of ignorance.



If you want to read amateur screenplays, go to zoetrope.com or amazonstudios.com and start reviewing. That's also a good way to get feedback from other amateurs.



There are plenty of bad screenplays out there, and they can teach valuable lessons on what not to do. But you should be trying to write like the professionals if that's what you want to be.
