LOTS more casting, Cassie!

The Dany actress looks NICE and is 21 rather than 14, so it should be fine to enjoy the sex scenes (and GRRM seems quite excited about the sex scenes.)
Theon Greyjoy looks like a bit of a prick, which is good! I hated him. Just realised he's Lily Allen's brother too.
I remember the Jaime actor from Virtuality (he was the commander, the main character for most of it until he died near the end, but came back as a hologram or whatever...I guess that show is never coming back) and he was good in that and hopefully will be good in this, as Jaime is my favourite character from the books.
