A remark about registering your copyrights...
At marvels Film we pitch concepts, scripts and formats to international business partners and other parties, and we don't want to risk our ideas being stolen.
As of april this year we date, register and certify all of our documents through ideaposit.com - a "DIY" copyright registration service. Even movie clips. We love it!
Protecting your creative works is important, DO IT!
It won't cost you a penny.
