I don't think you would have to worry about "Megan Fox fanboys" coming to see the movie just because of her. Although I'm in agreement with Josh that I don't care the reasons people come see the movie, just as long as they do.

The Transformers movies obviously raked in lots of money (and not because of Megan Fox), but everything Megan has been in since then has failed miserably, in the Box Office and critically. Teenage boys didn't go see Jennifer's Body, and virtually no one saw Jonah Hex, even though the marketing for both movies centered heavily around her. She doesn't have the following that people will see a movie with her in it simply because she's in it. If people aren't planning on seeing SC anyway, she is not a big enough draw to bring people into the theaters for the sake of seeing her.

Personally, I can't think of a particular actress that I see in the role. But I want whoever it is to be charming and beautiful, and disarming yet dangerous. Someone with natural beauty, who has the acting chops to bring the innocent and alluring and yet purely evil and manipulative aspects of the character to life.

On this page I really love the idea about having Summer Glau as LOTGK. She's gorgeous and portrays nice to bad very good.

Rebecca Mader is far far too innocent looking (and I will say the same about Kate Winslet. Though Rebecca does have a great voice so I wouldn't mind hearing her as a Narnian voice over like Hwin.

As voices go, this actress has my favorite speaking voice right now and she did just recently pull off playing a baddie. In this pic, she looks the part to me if you just stuck her in a green dress. Bryce Dallas Howard. I don't know why I keep picturing red heads now - must be the green dress.

Honestly I haven't been liking Bryce Dallas Howard's acting lately, but that may just be me. As far as her looks goes yes she masters what TLOTGK should look like.

honestly, i've never seen bryce dallas in anything, but i think she does really look the part. if she can act ( which i have no idea if she can ) then i think she would be literaly perfect

Bryce can act, but she aint right for the part.

Bryce has been playing some pretty mean roles. When Live With It comes out go and see it. She is so mean. I think she could make a good LOGK!

Bryce could actually be good! I just don't want people to think that Narnia is in any way similar to Twilight. The two should not be associated with one another!

Well, she's in plenty of other films (and has bigger roles in them!) so I doubt that would happen. Narnia films came out first.

I don't know about Bryce or Summer. They are both a favorite of mine, but it's no better for them to play LOGk if Megan Fox was to get the role. They are all too well known for their roles. Right now i'm sticking with unknown actresses until I see somebody that not a lot of people takes notice of.

an unknown actress could be great, it just depends what unknown actress they pick, because casting an unknown actress, who's any good could mean that without even knowing it they might pick an actress who's completely wrong for the part

They usually are pretty positive that an actor/actress is perfect for the part before they are cast. We might not think so, but the film makers would. If they pick an unknown actress for the part (which, now that I think about it, I might prefer), they would be very sure that she could play the part well.

I wouldn't say that either Summer Glau or Bryce Dallas Howard are all that well known. Summer is pretty much only popular in the niche scifi genre since that's basically all she's done. Bryce has had a couple of high profile roles, but she's not exactly a superstar.

I have to say that I like the idea of Rebecca Mader, who played Charlotte Staples Lewis (C.S. Lewis) in LOST. She was very ambiguous in that and mysterious - she's got unusual eyes - a perfect accent - and is quite beautiful. It would be a neat twist too.

I suppose I'm in the minority on this one, but I love this suggestion. One of my favorite things about Tilda as the White Witch is that she's so unusual looking. And that's why I love the idea of Rebecca. Very unusual.... and very lovely!

i sill support an unknown actress cuz you guys are probably right when you say they wouldn't choose a bad unknown actress, so i support her, whoever she is.
