Final Potter novel to become two films

UNDER the normal rules of mathematics, seven into eight doesn’t go, but if you’re a wizard, anything is possible.

Such is the spellbinding power at the box office of Harry Potter, that eight films are required to retell the tale of our wizard hero, the central character in seven bestselling children’s novels.

Previously, one novel equalled one movie, but the final instalment of the Potter saga is of such breadth, that its producers believe it would be an injustice to attempt to sub it down.
