From the clips I've seen on YouTube of Theodora (after the transformation), I thought Mila has got it spot on. Don't forget this a younger witch, not the older one we are used too. The laugh was brilliant too. But I need to see it in full so won't judge fully yet.
I agree, just saw it tonight and I thought she was great in it. I enjoyed the film but would have like it more if two idiots behind me hadn't chatted the whole way through. 'What's she been in?' 'Dawson's Creek'. AAAARRRRGGGHHHH!
