Keep in mind that Bettany's Elwë is *quite* tall, and Lúthien will have scenes with him. So, we probably don't want anyone too tiny.
Also, the discussion of how to introduce Lúthien will happen this Friday, most likely, and should cover the 'is-she-a-child-or-an-adult-when-we-first-see-her' question. Allowing a character to grow up is one way to show the passage of time, so it's possible we will want a child-intro, but it's just as likely we'll want an adult member of Thingol's court from the get-go.
It will also be interesting to see what type of personality we give to Lúthien. We are going to have her around for 2 full seasons (at least) before she meets Beren, so the audience will be quite familiar with her before her love story plays out. I mean, potentially. She may just be a minor background character. We'll see.
Lúthien should be a skilled dancer. Or at least someone who can pull that off. I realize a lot of actors are talented enough to sing or dance even if they never have had roles like that before, but I think that in her case, we probably want someone with some impressive portfolio when it comes to dance training, not the reliance that the stunt coordinator can make her look like a good dancer if she's not already.
Marielle - I agree that concepts of beauty are important here. There are some characters who are *supposed* to be stunningly beautiful. Snow White is a good example. Buttercup in the Princess Bride is another. If the narrator (or the other characters) are going to go on and on about someone's legendary beauty, then the audience is going to expect....a drop dead gorgeous actress. And almost no matter who you cast, you're going to get a lot of people saying, 'eh...she's not that pretty.' Which is annoying. But when you hold someone up as the pinnacle of beauty, there is an implied message there. Lúthien is a mixed-race character - that's an important part of her identity. While we do not have to cast mixed-race actress, we certainly *could* - and that would maybe be as faithful as an Edith Tolkien look-alike. It's certainly something that is worth keeping in mind. I think the more suggestions the better - we'll find someone who's a good match.
I have been trying to think of TV-casting-based-on-a-real-life-person, and all that is coming to mind is that Temperance Brennan of
Bones is based on Kathy Reichs.
Here is Kathy Reichs:
And here is Temperance Brennan (played by Emily Deschanel):
...and standing next to each other:
They really don't look much alike.
(Kathy Reichs is a forensic anthropologist and author of crime novels in which her main character - Temperance Brennan - is a forensic anthropologist who works with the FBI to solve crimes/cold cases.
On the show, Temperance Brennan is a forensic anthropologist at the Jeffersonian who works with the FBI to solve crimes, and writes fictional novels about her life featuring the adventures of an imaginary character named...Kathy Reichs.
The show is not based on the books - rather, the show is meant to base it's main character on the writer of the books!
Oh - and Kathy Reichs had a guest spot on the show and served as a technical advisor. So there's all sorts of recursion going on there.)
