No, we write the stories as well.
So, like, Avengers Assemble? I got an email saying I was invited to pitch on the series. I had a phone call with Tom where I got the basics of the feel they were wanting for the book (rotating roster, relatively short story arcs) and I had a few days to put together my pitch.
I wrote a paragraph on tone and themes, I think, then gave three sample arcs.
Two of the three you’ve already read if you’re following the series.
When you first start working with a company, you’re usually asked to turn in story outlines first. Once they’re comfortable with your style, they’ll generally let you skip that step — as long as they know and have approved the basics of where you intend to go. (This isn’t as Big Brother as people try to make it seem — editors need to co-ordinate for continuity, which is an impossible task under the best of circumstances. If you’re going to do something to change the status quo of a character, they really, really need to know as far in advance as possible.)
The writer then composes what is basically a letter to the penciller in the form of a script, describing the story…
And so on.
Does that help?
