Who do you want to see in the show? Do you want mainly unknown actors/actresses, established people, or some sort of combination? Any particular people come to mind right away?
I'd like to see some combination of new faces and known entities
Marisol Nichols could make an interesting Moiraine ... something about her carries that mysterious air to me
Camilla Mendes might make a good Egwene
For some reason I've been picturing Sheriam as a red-headed Asian woman in this most recent re-read ... no clue why, but lately I imagine her as a chubby red haired Lucy Lui
Archie Panjabi is too old for the role now, but she would have been a perfect Faile 15 years ago
Gal Gadot, who is playing Wonder Woman in the upcoming film, could make a nice Leanne
Christina Hendricks as Graendal
Kathy Bates might make for a fun Verin
And I could see Jessica Lang as Cadsuane
Sigourney Weaver would make a great Elaida I think
I struggle with the male characters because I think so many of the young men in Hollywood are sort of bland pretty boys for the age appropriate actors for Rand/Mat/Perrin ... the actors who may have been good seem too old now.
Mat ... I've always pictured someone like Josh Hartnett from 15 years ago as looking the part
Perrin ... I think they'd have to discover someone ... his physicality will be a challenge to find in such a young man how many 6'2 muscle bound 20 year olds are floating around out there?
Rand would be tough for a lot of the same reasons as Perrin ... the physically imposing build is hard to find in Hollywood right now, even if you give it a lot of leeway, one of the biggest things about Rand is his height, IMO missing the mark on that piece will be very obvious to fans, especially since his clear physical uniqueness is a big driver to his characterization early in the series.
