I doubt they’ll ever make the Wheel of Time into a TV series — but it’s an interesting mental exercise, thinking about how they would do it. (I do this sort of thing a lot, because it makes me think differently about story structure and how to create the appropriate shape.)
Up front: no way in hell would they just film it the way they’ve done with Martin’s books, (roughly) one book per season; that would make for fourteen seasons of TV, and even in a hypothetical scenario nobody’s going to do that. Even allowing for reductions based on things like “you don’t have to describe clothing when you can just show it” and “we’ll go straight to the meeting between these characters, rather than spending an entire chapter setting it up,” you’ve still got too much. Even if you go further and cut out a lot of the side viewpoints. You have to make it smaller. We’ll give them seven seasons to play with: that should be enough.
The next thing is that you have to restructure it. You can’t just condense the material and then film it straight through, because you’ve got to make sure the beats fall where they should. The end of every season needs to have something significant happening with the protagonist. I said in my discussion of writing long fantasy series that you need to hammer in some pegs for major events, and then navigate a path between them; in this case that means deciding what’s happening with Rand at the end of every season, and then shifting everything else to form a good shape around that. Theoretically the same should have been true of the books, but — well. Because of the way the structure got out of control, there are several books where the actual climax of the book is in somebody else’s plot strand.
Going through the series, what are his big events at the end of each book?
