The most recent issue of Emma Watson's newsletter is currently being sent out to her fans and Emma-Watson.net has a scanned copy in which Emma says:
I am now in the middle of filming the fourth Harry Potter film, The Goblet of Fire. I had a four-month break before this started and it was really good to go back to school and see all my friends, but now I am back at the studios it feels like I have never been away!
