Harry Potter and the Half-Blood Prince

What will Daniel Radcliffe look like in his 30s? You'll soon find out.

Radcliffe and his Harry Potter costars, Rupert Grint and Emma Watson, will be digitally aged for the franchise's final film using the same technology employed in the reverse-aging Curious Case of Benjamin Button, Hollywood.com reports.

"[W]e saw The Curious Case of Benjamin Button and that aging technology, so I think we'll try that because I'd feel terrible about having other people take those parts at the last gasp," says producer David Heyman.

The epilogue of Harry Potter and the Deathly Hallows takes place 19 years in the future, putting the characters in their mid-30s.

Though aware the transformation can be done, Radcliffe, 19, says he's wary about the idea and would prefer to have another actor play older Harry.

"If it's not good and that's what people are left with, that would be awful," he says. "If it came to a choice between having me, Emma and Rupert looking a bit stupid and it being slightly comical or having other actors play us, I would go for the other actors every time."

Split into two features, the second part of Hallows will hit theaters in July 2011. The sixth installment, Harry Potter and the Half-Blood Prince, opens July 15.
