MTV Movies Blog reported that the Epilogue for Harry Potter and the Deathly Hallows will be filmed and that the current cast will be used.
"'We will shoot it,' producer David Heyman confirmed for MTV News. Rowling wrote a flash-forward ending to 'The Deathly Hallows' that shows where the characters end up as they grow older. Heyman also indicated that the original Hogwarts actors would be filling those roles for the sequence, rather than being replaced by older lookalikes."
