Harry Potter reunion team admit to blunder with Emma Watson and Emma Roberts

Fans have been waiting 20 years for the Harry Potter reunion special which saw the original cast of the successful movie franchise - Daniel Radcliffe, Rupert Grint, and Emma Watson - reunite for the first time in two decades to discuss the magical journey they all went on from a very young age. But, one eagle-eyed fan spotted quite a blunder during the special causing some serious social media buzz.

Harry Potter 20th Anniversary: Return to Hogwarts hit HBO Max on Saturday, Jan 1. and fans of the magical phenomenon were eager to jump right into the reunion special, but as soon as the special began one fan realized that the production team of the show had made an epic blunder. The fan points out that right at the beginning of the special, an image - which producers presumed was a younger picture of Emma Watson, 31—appeared on the screen. However, it's since been confirmed that the childhood pic was actually of Emma Roberts, 30, not the Hermione Grainer actress.

Sharing the photo used in the special alongside a screenshot of the Scream Queens alum's Instagram post from 2012, one fan wrote on Twitter, "GUYS HELP ME THATS LITERALLY EMMA ROBERTS NOT EMMA WATSON." 

After the small blunder hit social media, producers for the reunion special addressed the tiny error in a statement to E! News saying, "Well spotted Harry Potter fans! You brought an editing mistake of a mislabeled photograph to our attention. New version is up now."
