1. Sirius Black, Remus Lupin, James Potter, and Peter Pettigrew were actually the ones who created the Marauder's Map when they were students at Hogwarts.

"The movies didn’t even mention that the Marauder's Map, such a significant piece of mischief, was made by Harry’s dad and his friends! It’s ABSOLUTELY NUTS to me that the movies didn’t even MENTION this!"

2. Albus and Aberforth Dumbledore had an intense sibling rivalry after their sister, Ariana, accidentally killed their mother. They competed over who cared the most about their sister. They dueled against each other, and when Ariana tried to stop them, Albus accidentally killed her.

"THE MOVIES COMPLETELY LEFT OUT THE DUMBLEDORES' BACKSTORY. They left out that Ariana Dumbledore showed signs of magic from a young age, but muggle boys made fun of her for it so she hid herself and her magic away. Her father killed those boys for hurting Ariana and he was sent to Azkaban. Ariana was sick and weak, so she never went to Hogwarts and everyone thought she was a Squib. Her magic strengthened, but she didn’t know how to control it, so she accidentally killed her mother. This should’ve been in the movies."

3. Harry, Ron, Hermione, and the Weasley family visited Arthur at St. Mungo's Hospital after he was attacked in the Department of Mysteries. They noticed Neville in the same ward, visiting his parents who were very much alive but driven "insane" by Bellatrix's Cruciatus Curse.

4. When Voldemort died in Deathly Hallows, he didn't disintegrate into a million little pieces — he died a mortal human being.

13. The Bloody Baron (Slytherin's ghost) was deeply in love with Helena Ravenclaw (Ravenclaw's ghost). When she ran away to Albania to get away from her mother, Rowena Ravenclaw, the Bloody Baron asked her to return with him. When Helena refused, he killed her and then himself.

"Throughout the series, there were passing references as to why the Bloody Baron was covered in blood and chains. It transpired at the end of the last book that he was in love with Helena Ravenclaw. Not only did [their relationship] explain how the Slytherin and Ravenclaw ghosts came to be, but it also explained why Voldemort was so focused on Albania and why Professor Quirrell was there before book one."
