Dessa here,

I think Katie McGrath is perfect,
but her hair is black not red, which I prefer red ,
but I guess they can dye it, which is good!

Wow, I'm surprised no one has mentioned Natalie Portman yet! She wasn't very good in Star Wars, but that was in large part to the absolutely terrible dialogue she was given. I've been hearing she was phenomenal in Black Swan, and is getting some award buzz because of her performance.

She has a very unique voice, too, and has been wonderful in all the movies that she has been in (except for Star Wars), and is the perfect age. She doesn't look too young, but it's not like she is pushing 40 like Winslet. She's only pushing 30.

Please, don't mention Megan Fox. She CAN'T act. Just because she is hot doesn't mean she should get the part. Winslet is a good candidate, but she is just a little bit too old.

I don't think Natalie Portman would really fit the part. Her voice isn't right. All the Narnians seem to have British accents and I've never heard Natalie Portman do an accent at all.

I think Asheley Greene would be good.

Yes, she is very pretty and "dark" ( I mean her hair, so she could look like I picture LotGK). Such beautiful eyes too, good thing for enchanting people. Almost to pretty to be a witch. 'Course, that's good for us not knowing yet. I'd love to see her looking like that for the innocent parts and then like "Rahr!" for the other parts.

*edit* This is the first time I have ever seen her, though. How is her acting?

Great! She´s Alice from the Twilight series! I think she could learn an accent!

There are a lot of really great suggestions here (I'd love to see Diana Argon in a Narnia film) but keep in mind, the actress has to turn into a snake and get her head cut off. Just sayin.

WHo cares if an actor is famous? Is Narnia forbidden from having any famous actors?For the most part I think actors, especially the kids, should be fairly unknown. But I think roles like Puddleglum, the Lady of the Green Kirtle, and Uncle Andrew should be cast by well known actors.

I agree about the kids but I would much rather not think, she did this, he did that why isn't she annoyed with him any more........ so they shouldn't be too famous or have been in films together before. Just my tuppence worth

Ashley Greene would be really good. she can play vicious and sweet.

i would enjoy seeing natlie portman as LOTGK.

I like the idea of Ashley Greene playing LOGK, she is really pretty.

My other choice would be Rachel McAdams.

After reading through this thread, I couldn't restrain myself. So I joined.
I'm not entirely sure who I'd like to be the LGK. There are several things that I know I do want to see in the actress, and a few things and people I wouldn't be able to bear seeing as the LGK.
Firstly- this is not necessary, just my silly idea- I think the LGK should have darker hair. I think a red head might hurt the eyes a little in a poison green gown. Black hair might be overpowering, remembering that this woman has spent about ten years, maybe more, living under the earth, only returning to the surface occasionally.
This leads me to number 2- she must be pale. A northern witch, living under the ground for a decade would have to be.
Thirdly- I don't think that the LGK and Jadis are the same person. Therefore, I think it would be a very big mistake to have her played by Tilda. IDC what you think, this is just my opinion.
Fourth- she needs some kind of accent, or something. American or British or European in general... It needs to be soft.
Fifth- the super "sexy" actresses are all fine, but I don't think they'd be appropriate for this role. LGK is seductive, sure, but remembering that 1) they are bound by contract to make this movie PG, and 2) Lewis wrote the CoN as a children's series, LGK cannot be "sexy". If anything, mere hints would work. Subtlety seems to be her strong point, so that's how I've always pictured her. Sweet, Innocent, yet dangerous. There's something dark lurking beneath the surface.
Sixth- I've always pictured her in her mid to late twenties or early thirties, or appearing to be. She appears young as a matter of choice. I mean, who'd want to look like a hag? No one willingly.

See, I can't think of a single actress who would do well at LGK off the top of my head, but Emily Blunt has been the best suggestion that I've seen. Maybe there is someone else that I just don't know of. -shrugging- Alright. Wow. I didn't intend for this to be so long.

Kathryn94511 lot's and lot's of agreement, you are right about the hair, red would be over powering and if she's to be pale, which she should be, blonde hair might make her too much like TWW. They should not even resemble each other and please, please, please don't let Tilda play LofGK. Another point on the accent, I would say Itlalian maybe or Spanish, a lot of rolling her r's a trilling sort of a voice with lot's of inflections but very gentle and enchanting. This is stupid, I'm pretty much just agreeing with you. I do agree with you about it all. P.S. (should have said this before) Welcome to Narniaweb

Emily Blunt gets my vote. She looks the part and from what we know, she could act the character very well. When, and if, they ever make SC, I'm sure they'll find the perfect LotGK. As long as they don't use Tilda Swinton, I'll be happy!

Katie McGrath or Emily Blunt would both be great, they both have what I think LotGK should have looks wise...

Katie McGrath looks like a really good LotGK
