Remember when Harry Potter reunions were just a rumor?

Several original cast members confirmed the news on Instagram, and fans are skipping with glee (at least I imagine so). First, Emma Watson posted the official teaser for a special program celebrating 20 years since the first film's release (the actual anniversary is November 16)." Had to take out the Time Turner one last time for this one... #ReturnToHogwarts, streaming only on @hbomax," Watson wrote.

Next up was Tom "Potta" Felton, who wrote, "Is this what school homecoming is like?" and "Mark your calendars for New Year's Day #returntohogwarts , streaming on @hbomax x"

Matthew Lewis aka Neville Longbottom wrote, "This year. New Year's Day... We're getting the band back together," he shared a teaser with the caption. Streaming only on #ReturnToHogwarts and @HBOMax. International release coming soon."

No word from Rupert Grint, and Daniel Radcliffe is not on Instagram, but they are both listed in the credits at the end of the teaser. Also in the cast are Helena Bonham-Carter, Ralph Fiennes, Imelda Staunton, and Bonnie Wright, among others.

Watson also posted the most adorable photos of the cast and crew, including photos of herself and her trusted companions Radcliffe and Grint, along with what appears to be the entire cast and crew. He wrote: "Harry Potter is my home, my family, my world, and Hermione was (and still is) my favorite fictional character. I think a journalist once told me that it annoyed him that during an interview I kept mentioning how lucky I was and started counting: ...... But I knew better! she wrote, bringing us all to tears for a bit.

She continued. 'I am so proud not only of what our group has contributed to the franchise as actors, but also as young adult children who have walked that path. I look at my fellow cast members now and I'm so proud of how we've all grown as human beings. I'm proud that we were kind and supportive of each other and held up something meaningful."

"Thank you to our fans who continued to support us after the final chapter closed. The magic of the world would not exist without you. Thank you for fighting to make it such an inclusive and loving place.

"I will always miss the crew that still made these films. I know your contribution will be overlooked at times.

"Happy 20th anniversary, Potterheads! Enjoy the 20th anniversary of Harry Potter: "Harry Potter 20th Anniversary: Return to Hogwarts" on HBO Max on New Year's Day, January 1. There will be lots of fun to be had."
