Oh, Neville, when are you going to stop breaking our hearts with your perfection?

The "Harry Potter" movie actors started as fans, and when Matthew Lewis isn't Neville, he's one of us. A hotter version of us, but still a fan who just fell in love with the world of Potter all over again.

Lewis is not a part of the stage play "Harry Potter and the Cursed Child" -- set after the events of the final film, "Harry Potter and the Deathly Hallows Part 2" -- but he saw the production and wrote a touching, heartfelt post on Instagram in its honor:

"A giant congratulations and an even bigger thank you to these guys and the rest of the cast of #CursedChild. To be in the movies was a dream come true but it became work and I forgot what it was to be a fan a long time ago. However, over the last two nights I was able to enjoy the world of Harry Potter once again. To lose myself in a story so rich and so powerful and, more importantly, that I had nothing to do with was truly magical. I felt like I was nine years old again, discovering it all for the first time and it is very, very special."

That's so beautiful. Here's the actor with the "Cursed Child" cast:

Matthew Lewis is far from the only Harry Potter OG to check out the two-part play on stage. Emma Watson praised the show, and the new Hermione, and Rupert Grint posed with the new Ron. Let's hope they enjoy the world of "Fantastic Beasts" just as much.
