When I write a script I usually have some very specific images in my head. Drawing them into one of my sketchbooks helps me define those images.
I would then note down some one-liners for every scene. Once this is done, writing the full script is the easy part.
However, for The Wendigo Effect, my science fiction horror movie, I´ve already written the full script some time ago. But I felt, that I have to accommodate to a more manageable budget. And as I will re-write the script anyway (no script is written, they are all re-written) I can work on the visual concept as well.
There are lots of sketched pages and I´ll scan some more as soon as everything is not as busy 🙂
In the meantime, let me know what you think about it in the comments!
