Emma Watson - the young actress who plays Hermione in the Harry Potter films - has backed the decision to give Goblet Of Fire an older kids' rating.

The previous three movies were given PG ratings, but Goblet will be a 12A because it's "darker" than the others.
Speaking at a press conference to launch the movie, Emma said: "We may have lost some of the younger audience, but I'm in it and I was scared!"
"It's much more of a thriller and we can't avoid that someone dies in it."
Emma was joined by co-stars Dan Radcliffe, who plays Harry, and Rupert Grint, who plays Ron, for the press conference in the ancient surroundings of Merchant Taylors Hall in the centre of London's financial district.
Also chatting about the movie were newcomers Stanislav Ianevski (Viktor), Clemence Poesy (Fleur), Katie Leung (Cho) and Robert Pattinson (Cedric).
Katie revealed that making Goblet had changed her life.
"Before all this, I was just a typical schoolgirl. I was really shy at school. Doing this has brought me so much confidence. I'm much more outgoing and outspoken," she said.
The cast members talked about everything from their future career hopes, to their fave bands to whether or not they were single.
The event, also attended by Goblet director Mike Newell and producer David Heyman, also threw up some interesting facts about the fifth movie - Order Of The Phoenix.
David revealed that filming starts in February and gave an update on the casting news.
"We are searching everywhere for the right Luna. We are also in discussions with Imelda Staunton about Professor Umbridge, but we don't know what will happen there.
"We also have in mind a Tonks and a Shacklebolt, but we haven't yet made a deal."
