We asked the BuzzFeed Community to tell us all the tiny details from the Harry Potter movies that most people missed. Here are some of their responses, along with some contributions from Reddit:
1.Ron's robes in Sorcerer's Stone are more faded than Harry's and Hermione's because they're hand-me-downs.
2.In Sorcerer's Stone, there’s a portrait of Anne Boleyn (who Henry VIII accused of witchcraft) in Hogwarts.
3. In Order of the Phoenix, someone in the background bumps into a Thestrel they can't see.
4.As Hermione is describing what the love potion smells like to her in Half-Blood Prince, the fumes change color to match what she's describing. However, there's a pause in her list when the fumes turn orange, the same color as Ron's hair.
5.When Oliver Wood releases the Snitch while teaching Harry how to play Quidditch, he immediately loses sight of it, but Harry keeps his eye on the Snitch, highlighting his future talent as a Seeker.
6. Harry, Ron, and Hermione dodge spiders, a troll, a werewolf, and dementors in Deathly Hallows Part 2, all creatures they fought in the first three films.
7.In a flashback in Order of the Phoenix, Sirius says, “Nice one, James,” when James disarms Snape. Later, after Harry disarms a Death Eater, Sirius says the same thing.
8. Some students in Order of the Phoenix are eating "Cheeri-Owls" cereal.
9.In Snape’s death scene, there's a Gryffindor scarf hanging up in the background, a reference to his bravery and Dumbledore saying he “sometimes thinks they sort too soon” in the books.
10.The ways Harry, Ron, and Hermione wear their scarves and ties reflect their personalities.
11. In the Warner Bros. logo for Goblet of Fire, you can see the pattern of Nagini's scales.
12.Hermione's hair grows throughout Deathly Hallows Part 1 to show how long she, Ron, and Harry have been traveling in search of horcruxes.
13.What Sirius tells Harry when he says goodbye in Prisoner of Azkaban foreshadows Harry's use of the Resurrection Stone in Deathly Hallows Part 2.
14. In the credits of Prisoner of Azkaban the footsteps of three different people can be seen running out of the Stink Bomb Store, presumably because one the bombs went off.
19.In Tom Riddle's room in the orphanage in Half-Blood Prince, there's a picture of some cliffs. Those are the same cliffs where Dumbledore and Harry travel to collect the locket, one of the seven horcruxes.
20. While the rest of the girl in Dumbledore's Army are wearing skirts, Ginny is wearing pants, probably because they're hand-me-downs from her brothers.
30.Professor Lockhart has a wig in his office in Chamber of Secrets, suggesting even his luscious hair is fake.
31. When Harry is inside of Tom Riddle's memories in Chamber of Secrets, there's still flickers of the candle that's sitting next to him in the real world.
34.In Tom Riddle's room at the orphanage, he has seven rocks lined up on his window sill, foreshadowing his seven horcruxes.
35. Lucius Malfoy instinctively pulls out his wand to defend himself in Deathly Hallows Part 2, but all he has is a broken half that Voldemort left him with.
