HARRY Potter fans could have double the magic to look forward to as the fourth book looks set to be made into two films.

Producer David Heyman has revealed The Goblet Of Fire could be split because the JK Rowling tale is so long.

Speaking at the DVD launch of the second film in the series - Harry Potter And The Chamber Of Secrets - Heyman said work on the film of the fourth book was under way.

He added: "We started work on the script last Monday.

"We're going to shoot it as one and see how it ends up. If it's too long then we'll make it into two."

Young Harry Potter stars Daniel Radcliffe, Rupert Grint and Emma Watson arrived at the lavish event in style as they were reunited with their famous flying car.

The trio made a grand entrance at Leavesden Studios in Hertford-shire in the schoolboy wizard's blue Hillman Imp from the film.

The youngsters last night looked taller and older than they did in The Chamber Of Secrets when it was released last Christmas.

Emma Watson, who plays Hermione, looked the typical teen actress in her designer gear.

Emma, who is 13 next week, wore leather hipster DKNY trousers and a midriff- skimming Moschino top.

But she was every bit the wide-eyed child star when she admitted to being amazed at how big the Harry Potter franchise had become.

"It's surreal when you're in London watching yourself go past on a bus, it's completely mad," she said.

"But I do know this has been handed to me on a silver plate. People go through trillions of auditions and never get here but I did."

Guests at the launch included Dame Judi Dench and TV presenter Ulrika Jonsson, accompanied by eight- year-old son Cameron.

They were all fascinated to see the Forbidden Forest and Hogwarts School recreated for the bash.

Scots star Robbie Coltrane, who played gentle giant Hagrid, was also at the launch of the DVD, which is set to become one of the biggest sellers of all time when it is released on Friday.

Online retailer Amazon have taken a record 40,000 orders before the DVD has even been released.

The movie took £52million at the UK box office.
