The massive global success of Avatar has rewritten the rulebook for making box office champions. Now, even the most successful film franchises are cribbing a page from that book, as Harry Potter goes 3D.

We’ve known for some time, of course, that the last two installments in the Potter franchise were going to have a third dimension, but now comes word that the earlier films in the series may get the same treatment. Potter producer David Heyman told MTV it’s “just a matter of time” before the complete series gets the in-your-face treatment.

“Those discussions haven’t yet happened, but I’m sure it’s just a matter of time,” he said. “You know what? I actually shouldn’t say that. Who knows? It would be great. You can never tell. I hope so.”

The final chapter in the Harry Potter saga, Harry Potter And The Deathly Hallows will be told in two parts. And though neither was shot in 3D, efforts are already underway to convert the films into the popular new format.

“Harry Potter is already an epic film,” said Heyman. “But having that added dimension will make it even more epic, and that seemed like an opportunity that was too hard to pass up.”
