The HBO Max special reunited favorites, including Daniel Radcliffe, Emma Watson, and Rupert Grint, but not everyone returned. Here are the celebs who were greatly missed.
Maggie Smith can be seen in archive footage, but that's it. She does not grace us with her presence during the reunion special.
One of the most notable absences was Michael Gambon. Gambon took over the role of Dumbledore after the death of Richard Harris.
Before he was Edward Cullen, Pattinson was in the Harry Potter franchise. These days he is busy gearing up for the release of his Batman film, so unfortunately he does not make an appearance in the reunion special.
It's unclear why Mrs. Weasley didn't make an appearance, but it is worth remembering that Walters largely retired from acting in 2020. This decision was made after a previously undisclosed bout of cancer.
