While promoting Half-Blood Prince in Greece Tom Felton and Evanna Lynch were interviewed by MSN.gr.  We have a rough translation but if anyone can do a better job let me know!

What is the secret of the success of both films Harry Potter»and books?
Tom: There are many things. Without doubt, the first is the story described in the book. The story is everything. But I think also part of the success comes from the fact that Harry is a normal boy uprooted from the natural world. Also, things which concern the characters are very human. The conflict of moral to immoral, the good and evil is always very good foundation for human stories.

Many say they see Luna in you. In what ways are you like Luna?
Evanna: Yeah, I know many say that and I take it as a compliment because I respect Luna too. She has inspired me and has an excellent philosophy where she remains calm and unaffected, which I am trying to adopt too. I never worry and never angry because I think she believes in fate and that everything happens for a reason. I also like that are very perceptive and know that people say that it is in its own world but not disappointed at all.

Thanks FeltBeats!
