The makers of the massively successfully Harry Potter series of films are considering splitting the fourth novel into two separate films.

The producer of HARRY POTTER AND THE GOBLET OF FIRE has revealed that pre-production is taking so long that the book may be made into two separate movies.

David Heyman was speaking at the DVD launch of the second Potter film THE CHAMBER OF SECRETS.

He says, "We started work on the script last Monday (31MAR03). 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."

The young cast of the film, including Daniel Radcliffe as Potter, were all at the launch party of what may become one of the biggest selling DVDs of all time. They all say they "cannot wait" to read Jk Rowling's fifth book, THE ORDER OF THE PHOENIX, out in June (03).
