Could this work?
I absolutely LOVE the book! I’m sort of interested in the prospect of a film adaptation, but you never know how something will come off in a different medium. Assuming they ever get a movie made, I’ll check it out with an open mind. It should at the very least be interesting to see how they portray the more fanciful parts of the circus. I’d especially like to see the cloud maze brought to life.
Also, I’d nominate Sadie Sink to play Poppet, though she may be getting too old unless the movie changes her age a bit.
