Since the thread has moved and it was me saying that the Green Lady and Jadis are the same I will end with this in an illustration by Pauline Baynes (who worked closely with Lewis) it shows Jadis from the magican's nephew, her wearing a green snake arm-let and the green ladys horse was white and called snowflake.
I know you're banned, but I will say this: if you're going to claim something, please back it up with evidence. If you can't find an online version of this illustration...then find it in a book. Otherwise, don't say it exists. I've never seen this so-called "illustration", and so it's either because it doesn't exist in your context, not at all, or I've never seen it in my versions of the books.
Now, your reasoning makes no sense whatsoever. "her horse was white and called snowflake"? That's your basis for The Green Lady and Jadis being the same? That's
very flimsy reasoning, and has a big enough hole in it to not hold any amount of water. Thank you, but no: you will never convince me that Jadis and the Green Lady are one and the same with baseless examples such as that.
EDIT: I did a little Wikipedia research, and did find the illustration probably referenced; however, a little arm bracelet is little reason to conclude that Jadis and the Green Witch are the same person; if anything, it reinforces the fact that since TMN is a parallel for Genesis in the Bible, Jadis is the serpent in the Garden of Eden. Also, I should say that in the image I found, the detail is not there to determine that Jadis is wearing a serpent bracelet. It doesn't even look like a snake from a distance, let alone up close. I blew it up to about 130%, and couldn't tell anything about it other than it being green. I'm sorry, but if they were the same person, Lewis would have written it as such. As it stands, I tend to go with the author's words. She was just a Northern witch, similar to Jadis. I think anything else would be grossly speculative and mostly wrong.
Anyway. I feel like this topic got way off subject. If (and a big if) there is another film to be released, will it matter which one it is? I feel like with Dawn Treader, they've kind of blown the franchise. Should there be a reboot of Prince Caspian and Dawn Treader, then a continuation? LWW was so well done, I don't feel that it needs a reboot. But, if someone could make LWW as well as Adamson (or even better, as I hated Tilda being the WW), then I'm all in. Thoughts?
