Harry Potter 20th Anniversary: Return to Hogwarts was a beautiful reminder of what it felt like to be part of the Harry Potter world in the beginning.
But the nostalgia was ruined, as one Twitter user noticed:
"Not the editing crew on Harry Potter 20th Anniversary putting a photo of f**king Emma Roberts as a child, not Emma Watson. I'm screaming."
The Twitter was loaded with questions, as one user wrote:
"But my goodness, couldn't the producers/writers/whoever fact check? They showed a picture of young Emma Roberts thinking it's Emma Watson."
A third added:
"They put the famous Emma Roberts picture in the reunion that almost everyone thinks it's Emma Watson, What the actual f**k? I can't believe this."
Apart from this obvious mistake, the reunion went backstage, and the particularly cute moment was Emma Watson confessing her crush on co-star Tom Felton, who played Draco Malfoy.
She was 10, and he was 13, and though nothing happened, they remained close friends. Emma gushed:
"I walked into the room where we were having tutoring and I just don't know how to say it - I just fell in love with him."
"I used to come in every day and look for his number on the call sheet, it was number seven, and if his name was on the call sheet it was an extra exciting day."
The mistake was fixed after the Twitter meltdown.
