Let's say I want to make a comic book and I want to make it long enough that it could fit into one full movie. How many total pages, chapters and volumes should I aim for?
Based on what I have read about script length, you need approx. 100-120 pages of content. Though it can be as long as you like. I would not worry to much about volumes and chapters, as a lot of stuff gets cut out when making a book into a movie.
