Superheroflix have an interview with Eva Green, who is playing Serafina Pekkala in The Golden Compass movie. The bulk of the interview is about her turn in the next Bond film, Casino Royale, but she has some things to say about His Dark Materials too:

“I'm playing Serafina Pekkala, a good witch, a very wise character. I hope the studio will be brave enough to bring the darkness and not make it a new Harry Potter. It questions religion and God, so we'll see what they do with it. But the first script is really good.” Read more.

EvaGreenWeb also tip us to Eva talking to The Telegraph a few days ago about her witch training: “Serafina has to just drop [to land], and I always have problems, even on swings and rollercoasters. So this is the most challenging thing. It's very fast.”
