The upcoming "Harry Potter" reunion special is fast approaching, and Rupert Grint is teasing fans about what they can expect.

The actor, who played Ron Weasley in the series, told "Entertainment Tonight" it was emotional to reunite with Daniel Radcliffe and Emma Watson for the first time since the final "Harry Potter" film in 2011.

"Those movies were our childhoods. We grew up on those sets so it has incredible meaning to all of us," Grint said. "It's been 10 years since we wrapped the last movie and we've seen each other quite a bit in-between that but not a great deal."

He added, "So it was great to see them again and talk about it. I don't really talk or think about it a lot, so it was fun to remember."

Addressing talk of possible reboot or sequels to the film franchise, Grint said he wouldn't be opposed to playing Ron again as he can connect with the character more now as a dad. Grint and his partner, Georgia Groome, welcomed a daughter in 2020.

"There's been a lot talk of [playing Ron again] with everything going on and I feel like I am that character," he said. "I think I had a very strange relationship with him at first but I feel like there's a lot of me in there so I'm quite protective of him. I don't really have a good reason to say no, I'm very proud to be a part of it."

"Harry Potter 20th Anniversary: Return to Hogwarts" premieres Jan. 1 on HBO Max.
