What stages do you go through when writing a script?
Mine are:
Original topic inspiration. I have lots of idea when walking or driving or whatever. Sometimes one idea seems a bit more of a goer than the others and I want to put it down on paper. (Or in a computer file)
Rough scribbling. I think of the first episode and jot down 20 lines of roughly what I want to happen in the story. A few key situations and the main story lines, and any good joke I can think of.
Detailed plan. 3-5 pages of A4 in my notebook. A scene by scene account of what is happening, who is where, and what has to be done and said for the story to work. I come back and revise this plan a few times and shift scenes about and make notes of jokes I want to get in. This bit definitely seems the most like proper hard work.
Write the script. I write the script out in the correct format. This is the bit where I add the jokes that come from the interplay of the characters. And of course all the other words and action that make the whole thing work and be 'real'. It's by far the most fun bit and comes pretty easy.
Rewriting. I leave it alone and try to forget about it, then try to read it with fresh eyes and make changes. Repeat as necessary.
How do you guys do it?
