1. Finn's stormtrooper name (FN-2187) is also Leia's cell number.
Sneaky sneaky.
2. E.T. in the senate chamber.
You can spot these aliens from E.T.'s homeworld in The Phantom Menace.
3. Maz Kanata's flags.
Outside of Maz's castle, there's an array of hidden flags, including Boba Fett's Mandalorian skull symbol.
4. The dice hanging in the Millenium Falcon.
Some traditions transcend galaxies.
5. George Lucas (and family) cameos.
Here you can see Katie Lucas and Geroge Lucas (left) and Jett Lucas (right). However, the Lucas kids pop up more than you'd expect.
6. Hieroglyphics on Tatooine.
It's unclear who put them there, but our money is on the Tusken Raiders.
7. Stormtrooper bumping his head...
Can these guys do anything right?
8. ...and Jango Fett bumping his head.
I guess it's hard to see out of those helmets.
9. Space Pod from 2001: A Space Odyssey.
This hidden movie prop can be found in Watto's junkyard.
10. Han's name is often pronounced differently.
Check out the name count here. Important: Lando always says it as if it rhymes with "plan," so Donald Glover BETTER emulate this in Solo: A Star Wars Story.
11. John Ratzenberger is in Empire.
There's Cliff Clavin literally chilling out on Hoth, which means Pixar isn't his only Disney staple.
12. Blue milk makes an appearance in Rogue One.
Aunt Beru would be proud.
13. The crowd-surfing stormtrooper.
Okay, so it's possible that they're just tossing around a dead body, but maybe he's a reformed stormtrooper, like Finn. Either way, you can catch this moment at the end of the digitally remastered version of Return of the Jedi.
14. Rian Johnson, director of The Last Jedi, has a Rogue One cameo.
He's one of the Imperial officers who works in the Death Star firing chamber.
15. Vader never says "Luke, I am your father."
He actually says, "No, I am your father." Check it out here.
16. Jessica Henwick has a cameo in The Force Awakens.
Yep, that's our girl, Nymeria Sand.
17. The hidden shoe and potato in Empire.
Rumor has it, the SFX people were annoyed with how many times George asked them to redo the scene, so they threw these in.
18. Warwick Davis is more than Wicket.
Overall, Warwick has played seven different characters in the Star Wars films.
19. Coruscant in Rogue One.
During Jyn's flashback, you can see that her family and Krennic are on Coruscant, a prominent planet from the prequels.
20. Lando steals Han's clothes at the end of Empire.
Bold move, bro.
21. You see the numbers 1138 quite often.
This is a reference to George Lucas' first film, THX 1138.
22. Jeremy Bulloch (Boba Fett) also appears in The Empire Strikes Back as an Imperial Officer...
Maybe he's just another clone of Jango!
23. ...and in Revenge of the Sith as a pilot.
He's catching up to Warwick Davis.
24. The Millennium Falcon is in Revenge of the Sith.
If you blink, you'll miss it.
25. Kanjiklub in The Force Awakens are the badass actors from The Raid movies.
If you haven't seen The Raid films, they will change the way you look at action movies.
26. Red Five in Rogue One.
Once Pedrin Gaul dies during the Battle of Scarif, the Red Five callsign becomes available and is eventually taken by Luke.
27. If you look really hard, you can see Judah Friedlander in Maz's castle.
It's hard to recognize him without a trucker hat.
28. Rey's goggles were repurposed from a stormtrooper helmet.
She's so practical!
29. Thomas Brodie-Sangster has a cameo in The Force Awakens.
Yup, that's Jojen Reed from Game of Thrones (or Sam from Love, Actually).
30. Han gropes Leia.
I know they're in love, but she had just been SHOT.
31. And, weirdly, the number of Yoda's toes changes.
As you can see from these toys, Yoda's feet have no consistency.
