The final sequence in Harry Potter And The Deathly Hallows is set 20 years in the future and features many of the main characters as adults.
Speaking to MTV News, he said: "We haven't shot that yet, and I still haven't had the confirmation whether I'm doing it or we're going to get someone else to do it.
"I haven't heard too much. I guess they're still making decisions about it now. It is a very exciting scene. I know Daniel [Radcliffe] and I have talked about it and said it'd be a lot of fun to do... It'd be kind of freaky to see what they come up with."
Director David Yates previously insisted that he will not recast the stars for the final scene, explaining that there was "something extraordinary" about watching their transformation from children to adults.
