Ok, so, if the film could be the way I want it, what would I like to see? I haven't really thought about it much.
How should the film start? Opening logos and then fade in to a dull autumn day? Then show two kids escaping bullies and calling out to Aslan? Well, there are a number of ways this could be shown. I want to see Eustace and Jill calling out to Aslan with deep sincerity, like a child would call out to God. Jill needs to be sold on the idea of Aslan, or at least open to it, not just going along with Eustace's wishes.
But visually, how should the film begin. Should it begin with a bang, like LWW or PC? Or should it begin clean and simple, like VDT (I really liked the way VDT began, it was the last 90 minutes of it I had a problem with). More likely it will start simply. The only really dynamic opening I can envision is an aged Caspian talking with Aslan and setting sail. Or of course the film could begin with the story of Rillian and his mother. I really like how the BBC did that story as a flashback (I thought it was one of the best parts of the BBC version) but it could also work at the beginning too.
I don't want to see any battles. PLEASE no battles. There are no epic battles in The Silver Chair by C.S. Lewis. Please don't have battles in The Silver Chair the movie. Please please please please please...just don't.
What else? Stick to the plot. Use Will Poulter again. Ben Barnes was like 100 so it shouldn't be a problem to have a 21-year old Eustace. The kid looks young anyway. About the Lady of the Green Kirtle (I don't think she's ever called "the green witch" in the book), it's okay to say she's of the same "crew" as the White Witch...but please don't make her out to be Jadis' long-lost twin sister.
What I really want to see included is all the scenes after Jill, Eustace, Puddleglum, and Rillian emerge from underground. BBC version skipped over this. These are beautiful scenes...emerging at night to a full moon and snowfall, and then the dance, and then everything in the chapter "The Healing of Harms."
This is a great story. It has a lot of potential. I hope they get it right.
