1. Whenever you turn in your script, is there an implicit understanding that it is final and cannot be changed? Or is it the contrary, i.e. there's an implicit understanding that it can be changed? Does the director (or whoever else) usually end up deviating from it? If so, do they need your permission before making any changes? These are the questions that came to mind on this topic but please feel free to elaborate some more as needed.
Why, silly boy, art DEMANDS that it be changed. You know ... improved, polished and made what you really intended it to be ... usually by a producer with "creative" ideas. If you're lucky, it may actually resemble the original story you wrote.
2. I am leaning towards Sophocles for my formatting software. I've read somewhere that some producers ask for an electronic copy in the Final Draft file format (.fdr I think). Is that still true? (Although, if it is true and the person has paid me for optioning the script, I'd probably just go buy myself FD if/when that request comes to me). Or do they now usually ask for .txt, .rtf, or .pdf if they want an electronic copy? Or do they even ask for electronic copies?
Yes, they all of the above. Most people want to hold a script in their hands.
3. Where do you get your 3-hole punched paper? The Writers Store carries them - $7.99 for 500 sheets. But I also found some 10-ream cases on Amazon that sell for only $50+ (not sure about the shipping yet though). My question is, is there a specific type of paper that I MUST use? Is there a specific brightness level? Is recycled fine? Must I invest in a good puncher instead? I have one that can only punch three sheets at a time. So, there's no way I can use that. But I was wondering if there's a puncher that you guys use and recommend.
Since they charge almost double for the pre-drilled holes, buy a good paper punch once and use it for 20 years on cheaper paper.
