Eagle-eyed Harry Potter fans spotted a major cock-up in the 20th anniversary reunion show after an image of another actor was shown on screen instead of Emma Watson.
The highly-anticipated Harry Potter 20th Anniversary: Return to Hogwarts caught up with the stars of the hit movie franchise two decades after it all kicked off - much to the delight of Potterheads.
However, some viewers were left confused when a snapshot of what was meant to be a young Watson flashed on screen.
Watson, who played Hermione Granger in the films, was discussing her childhood when an image of a young girl wearing some Minnie Mouse ears appeared on screen.
While very adorable, the photo is very much not Watson and is actually an image Emma Roberts posted of herself on Instagram a while back.
And it didn’t take long for fans to notice, posting on Twitter, one person wrote: “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.”
Someone else asked: “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 wrote: “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.”
Elsewhere in the special, Watson revealed that during filming she ended up developing a huge crush on her co-star Tom Felton, who played Draco Malfoy.
"I used to come in every day and look for him," said Watson.
"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."
She went on: "I walked into the room where we were having tutoring. The assignment that had been given was to draw what you thought God looked like, and Tom had drawn a girl with a backward cap on a skateboard.
"He was three years above me and so for him he was like: 'you're like my little sister'."
Not what you want to hear from someone you fancy, is it?
