I fell in love with the idea of Monica Bellucci being Melisandre but Ruth would be a good choice too. Other than Gillian and Emmanuelle I don't know these other actresses, except Katie. I love her on Merlin but that's probably because I don't really expect a lot from that show so whenever I see Colin do something brilliant it's wonderful and I forget that well Katie's not that good an actress, lol. I think they've done such a good job with all their casting that she'd really have to impress beyond her beauty. There are so many beautiful actresses out there who can act very well too.
