The Harry Potter reunion, with stars from the franchise such as Daniel Radcliffe and Rupert Grint, was the highlight of the new year for many fans.

But the 20th anniversary special was not without a few mix-ups. Most notably, a childhood photo of Emma Watson was shown, but it was actually an image of actress Emma Roberts. Now the "Hermione Granger" actress has reacted to the mistake.

Harry Potter reunion photo mistake: Emma Watson responds

It turns out Watson is laughing off the error in the Harry Potter reunion. The actress shared the childhood photo of her fellow actor on Instagram and writes: "I was NOT this cute [...] #emmasistersforever."

Immediately after the gaffe, however, things looked different. After a fan pointed out the mistake, there was a lot of criticism online, and HBO Max reacted swiftly.

The producers switched out the image and made it clear: "Well spotted Harry Potter fans! You brought an editing mistake of a mislabeled photograph to our attention. New version up shortly."

So maybe all the fuss was for not. After all, even Emma Watson found humour in the mix-up.
