I love the way they've done this trailer! The letters, a summons, "it's time to come home, everyone." It all feels so nostalgic.

Even after all these years the magic of the Harry Potter theme never fails to make you feel like a kid

Harry Potter isn't just a film series, it encapsulates a time, a place, a feeling...

It's so nostalgic. We all have grown seeing Harry Potter movies. Surely we're gonna Love the reunion Potterheads.

Feels so nostalgic, especially hearing the song! No matter how many times I hear it, it always makes me smile. Can’t wait to watch this!

Can we have a moment of silence for those who passed away:

Words can’t describe how happy I am. Just seeing the names Daniel Radcliffe, Rupert Grint and Emma Watson together again gives me goosebumps

I was sitting and reading comments to this video about 20 minutes. My heart warmed with the realization that people see the hypocrisy of these "actors".

I got so excited to see this. At first I was in denial and then I realized its legit. And then I remembered Alan Rickman as well as other lovely actors passed. But then I realized it's a reunion and I'm excited for it. Such a plethora of alternating emotions.

I was 9 when the books came out. I read them all and can honestly say that those books helped establish my love for reading at such a young age! Now, i'm 30 and to this day I have not enjoyed a series more than the Harry Potter series!

it doesn’t even feel like that long ago lmao, imagine being apart of one of the most culturally prevalent film series ever…that’s iconic

For those wondering, this is not a sequel, it's like a reunion with the cast like what friends and Prince of Bel air did

J.K Rowling is a creative genius. She filled all of our childhood with magic, literally.

My family has this tradition of watching the series every holiday season since I was around 3 years old, at that time there were only 2 hp movies and it's one of my earliest memories. I'm 21 now, and I'm still waiting for my acceptance letter like a child.

I don’t cry, but I shed a tear watching this. Harry Potter was major within my childhood. Wish all the actors the best In the future. Sad to see some of them getting old.

I remember watching the first movie when I was 10. This franchise changed my entire life. I’m so glad I grew up in the HP era

If you are a fan of harry potter you know exactly what it means to us even after so many years i want to see them together i feel so down because many of them are not presents in real life but still can give goosebumps whenever i start playing this series lots of love to them who can made it possible ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

Still after all the years, the sound of the song invokes a magical feeling in me, like I’m a kid again.

This makes my heart beats faster... Quite nostalgic as I remember watching Harry Potter movies in theater with friends and remembering it was blockbuster movie. Watching it umpteen times and still love it... 💙💙💙💙💙

YOU KNOW PEOPLE WE ARE THE LUCKIEST TO LIVE IN THIS ERA OF HARRY POTTER SERIES ❤️ NOBODY WILL KNOW HOW GREAT OUR CHILDHOOD WAS !!
