OP here.
Thanks for taking the time to check out the project and for your very insightful comments. It appears like Amazon's storyteller was discontinued in 2015 so it didn't end up being as useful as promised.
I think the real power is in what you described: "how to translate the story from script to screen for optimum storytelling power and production cost." This is a nuanced question because that translation seems difficult to get right (how does one incorporate signals about production cost, etc.) Would love to get more of your thoughts here.
