Cool! Now, whom is playing Lan?? Pike will kill it, she always does in the roles she does. Whomever plays Lan must complement her.

She can't just be confident and cold. She has to be caring, genuine. She has to appear to be colder at first, but unbelievably pressured and unsure behind the scenes. Her character could make or break the first book. 

Seeing some of her other movies, I can see her being able to pull it off well. Also to note,  you don't really see Moiraine "unbelievably pressured and unsure behind the scenes" in the first book. It is more when Rand starts doing his own thing, not revealing any of his plans, that she shows more expression outwardly than just being "cold" and emotionless. Minus private conversations with Lan. Even with that, as with most Aes Sedai, those expressions are very small. I would say she conveys her genuine care by her actions in the long run more than her outward appearance.

I always imagined Lan similar to how Viggo Mortensen portrays Aragorn in Fellowship of the Ring.

I think she's a wonderful actress but she really doesn't even come close to Morraines character description. One of the great things about Morraine is how she shows throughout that her diminutive height in no way makes her less capable... and often is used for her advantage to disarm people. I hope to hear this musical voice she has. Such an endearing character full of strength and passion.

But what about the height? That should be a problem.. 5'2 (as described in the books) vs 5'9 for the actress. This would make Lan almost 7 feet tall. If you take the given heights for the people. May  as well make Moiraine taller than Lan... How about making Lan 5'2 and Moirane 6'4? Sounds about right.  

I think this is great news.

I'm starting to get slightly worried about the casting announcements, the show is supposed to start in a couple of months and there have been no further casting news. Saying that I would love to see Sofia Boutella in the show. 

i think she is a bad choice she is way to tall to play Moiraine

I think the actor who portrays Lan nails that character, and it is because of Rosalind and the sets, etc. as well as poor review from avid book readers that I am now already reading book four. I was very busy to miss these books when they were first published. However, I KNOW I will read the entire series by the time season two emerges and will have more input. However, I think overall good job on the TV series because there is no way to replicate the books. It is much like a historical drama series. When you are a deep diver like me, you have to appreciate what they do get right and just let some things go. Quite tricky.
