I remember some years ago there was a controversial cover for an ebook of Anne of Green Gables. It portrayed the title character as a blonde. The mental image of Aslan as a lioness reminds me of that cover.

What I really don’t support is the idea of review-bombing or actively rooting for a movie to fail before we even know what it is.

Well said, and I'm still bearing in mind that we have no confirmation either way of whether the "female Aslan" rumour is true or not, from anyone at all connected with the film project.

I think the main concern for me, as I've said already, is this lack of comment from those in charge. They really don't seem to know how to manage their PR, which is very surprising and unsettling.

I'll be using the contact info that NarniaWeb has provided to write a few letters / emails over the next few days and, along with setting out the basic reasons why casting Aslan as female (or female-voiced) is not a good idea, I will be writing with the acknowledgment that this is still only a rumour so far, and will ask them straight out for whatever clarification they can give on what is actually being done.

If enough of us ask for that — rather than just assuming the worst and spitting flames, however much we may be tempted — then hopefully, someone at Netflix will see the sense in making some kind of public statement about this.

Even if it IS confirmation of my and others' worst fear — that Aslan is definitely going to be portrayed as a Lioness — then, well, at least we'll know where we stand. But hanging on as days go by and there's no new news whatsoever is becoming almost downright painful.  

Well, nothing has been confirmed, but I certainly wouldn't want a female Aslan! That would make Narnia seem out of place, and it would make absolutely no sense! Oh, don't get me wrong. There are some, well, male characters that I wouldn't mind being changed to a female if done in the right place at the right time. Plus, I would be fine with seeing a lioness (not Aslan, but a side character), especially in that scene in MN after the creation of Narnia where all the animals are gathered around Aslan, and it seems to indicate a male and female each (meaning there was a male and female lion together).

i do think Meryl Streep is a good actress, and she could end up being in the new Narnia film, maybe Aunt Letty. But a female Aslan would be crossing the line!
