‘Harry Potter’ Reunion Botched By Major Emma Watson/Emma Roberts Mix-Up

Even wizards make mistakes, but this one is a little more dark magic, than light: during HBO Max‘s Harry Potter 20th Anniversary: Return to Hogwarts special, a childhood photo of Emma Roberts was used instead of a photo of Hermione Granger herself, Emma Watson.

After a fan tweet pointing out the mistake went viral on Twitter, the producers of Return to Hogwarts promised to set things right. “Well spotted Harry Potter fans!” the producers said in a statement to Entertainment Weekly. “You brought an editing mistake of a mislabeled photograph to our attention. New version up shortly.”

Return to Hogwarts marked the 20th anniversary of the first Potter film, Harry Potter and the Sorcerer’s Stone, reuniting the cast members for some magical nostalgia. The special also revealed some behind-the-scenes bombshells, from Watson’s childhood crush on costar Tom Felton (who played Draco Malfoy) to the revelation that Watson considered quitting the franchise before the fifth movie.

“I think I was scared,” the actress told fellow actor Rupert Grint of her initial hesitation to finish the series. “I don’t know if you ever felt like it got to a tipping point where you were like, this is kind of forever now. The fame thing had hit home in a big way.”

Ultimately, though, Watson said that no one had to convince her to stay onboard the Potter films. “The fans genuinely wanted you to succeed and we all genuinely have each other’s backs,” she said. “How great is that?”

Harry Potter 20th Anniversary: Return to Hogwarts is now available on HBO Max.
