This post contains spoilers for Fantastic Beasts and Where to Find Them.
1. Gellert Grindelwald. Just kidding, you didn't miss this one. But to refresh your memory: Grindelwald was a friend and colleague of Albus Dumbledore's. Together they tried to find the Deathly Hallows, but Grindelwald became consumed by a desire for power. After Dumbledore's sister Ariana was accidentally killed in a duel between the two of them, Grindelwald fled England and became a Dark wizard à la Voldemort. Along the way, he found the Elder Wand but lost it to Dumbledore when he defeated Grindelwald in another duel.
2. Leta Lestrange. Leta briefly appears in a photo in Newt's suitcase hideout. He describes her as an old friend that he hasn't seen in a while because "people change." Given that Zoë Kravitz has been cast to play her in at least one sequel, it seems likely you'll learn more about that story in a future movie, but for now, you'll just have to speculate about how she's related to Bellatrix.
3. Newt's bowtruckle pal. One of Newt's favorite fantastic beasts is a bowtruckle, who clings to his jacket even when he's supposed to be hanging out with the rest of the bowtruckles. They don't appear in the Harry Potter movies, but in the book version of Order of the Phoenix, Professor Grubbly-Plank teaches the fifth years about them during Care of Magical Creatures.
4. Albus Dumbledore. He comes up in Fantastic Beasts as having been one of Newt's professors at Hogwarts. He doesn't appear on screen but it's clear he already has a reputation for being kind of wacky.
5. Newt's Hufflepuff scarf. When Mr. Scamander sets his suitcase to "Muggle-Worthy," you can see the black and yellow scarf neatly tucked in with his belongings. He also wears it at the end of the movie. Hufflepuff pride!
6. The Deathly Hallows symbol. Now that you know Percival Graves was Grindelwald the whole time, it should come as no surprise that the Deathly Hallows are involved. When Percival/Grindelwald is trying to convince Credence to help him out, he gives him a necklace with a charm of the triangular symbol. Stay away, Credence! That symbol means nothing good.
7. The niffler. As you know if you have seen it, Newt's mischievous niffler is the true star of Fantastic Beasts. Like bowtruckles, nifflers never appeared in the Harry Potter movies, but they were in the book versions of Goblet of Fire and Order of the Phoenix. In GoF, Hagrid taught his Care of Magical Creatures students about them using leprechaun gold, and in OotP, Lee Jordan set them loose in Umbridge's office.
8. The murtlap. When Jacob Kowalski accidentally takes Newt's suitcase back to his apartment, a murtlap escapes and attacks him, leaving him unconscious. This isn't the first time you've heard of a murtlap though — in Order of the Phoenix, Hermione uses murtlap essence to treat the cuts on Harry's hand after his detention with Umbridge.
9. The erumpent. One of the beasts living in Newt's suitcase is an erumpent, a large, horned creature that looks a little bit like a rhinoceros. When it escapes, it goes on a rampage through Central Park that culminates in Newt trying to lure it back into the case with a mating dance. But erumpents were first mentioned in Deathly Hallows, when Harry, Ron, and Hermione went to Xenophilius Lovegood's house. Xenophilius had an erumpent horn in his house but thought it belonged to a crumple-horned snorkack. Hermione advised him to dispose of it because erumpent horns contain a dangerous, highly explosive fluid. Xenophilius didn't listen though and the horn exploded, causing his house to blow up.
10. Squibs. You may remember from Harry Potter that Squibs are people born without magical powers whose parents are wizards — notable Squibs include Mrs. Figg and Argus Filch. In Fantastic Beasts, Percival believes that Credence is a Squib but eventually he's proven to be an Obscurial instead. An Obscurial is a young wizard who does have magic but suppresses it. Now remember Dumbledore's sister? Before she died, some Muggle children saw her doing magic and attacked her. She was never able to do magic again and this is how Aberforth described it: "She wouldn't use magic but she couldn't get rid of it; it turned inward and drove her mad, it exploded out of her when she couldn't control it, and at times she was strange and dangerous." Is it possible that Ariana was actually an Obscurial?
11. Quidditch. There's no Quidditch in Fantastic Beasts because Newt's too busy catching rogue creatures but that doesn't mean he doesn't still think about every wizard's favorite sport. At one point, someone asks him if he's a seeker, and he replies, "I'm more of a chaser, really." Well played, sir.
