Like many of us, you’ve probably watched the Harry Potter movies more than once. Or more realistically, thousands of times! But even if you’re the most eagle-eyed HP fan in the world, the genius creators behind these movies have put so many hidden clues in the movies.

We’ve put together some of the biggest and best hidden Harry Potter details that you probably missed.
Grey Gowns
Remember this scene, a typical day in the Dursley’s kitchen? In the background, we see Aunt Petunia stirring something feverishly in a pot. You probably didn't think too much about it, or even notice or wonder what she was cooking back there.

But in fact, she isn’t cooking anything at all—she’s dyeing Harry’s school uniform grey! This is a detail that’s only mentioned in the book, so only hardcore fans would know about it.
Magic Necklace
It’s not till pretty far into the story of Prisoner of Azkaban that Hermione reveals the truth of how she’s been getting to all of her classes—with the use of the magical Time-Turner that she hides on a necklace beneath her robes.

But if you look very closely, you can actually spot her necklace in this very early scene! Although it’s not till much later that we learn what it is.
He Who Must Not Be Hugged
Who can forget the impossibly awkward and cringe hug between Draco Malfoy and Voldemort in Harry Potter and the Deathly Hallows Part 2? Certainly not us! But did you know, not everyone realizes that part of the reason this was so awkward was that it wasn't planned in the script at all.

That’s right—Ralph Fiennes just ad-libbed and decided to hug Tom Felton on the spot! So cringe in the best way.
Art for Art’s Sake
We all love Dawn French’s performance as the Fat Lady, the inimitable figure in the portrait hole that leads to the entrance to Gryffindor Tower. But what you might not have noticed, is the portrait hanging right next to her!

Because this isn’t merely just a piece of filler—it’s actually art depicting some real people! In fact, this woman and baby are no less than the wife and daughter of director Alfonso Cuarón.
In His Shoes
When Harry and Dumbledore travel to Slughorn’s house at the beginning of Harry Potter and the Half-Blood Prince, he tries to evade their attempts to lure him back into teaching, but disguises himself as an armchair. As you do.

But only eagle-eyed fans and viewers will be able to notice a key clue that this sofa is actually a person—because Slughorn’s shoes are still visible!
In the Family
Did you ever notice this random wizard at Hogwarts before? What’s he doing there next to Lee Jordan? Very random and we have no idea what character he is supposed to be—just an unnamed person watching Quidditch.

But what you might not know, is that this seemingly random extra is a key member of the Potter family in real life. Because this actor is Nigel Anstey—and he’s Tom Felton’s real-life grandpa!
