The Toy Story movies are some of the most iconic children's movies ever made. I feel like just about every kid has seen at least one of these incredible movies.

Usually, when you're watching a movie, you don't pay attention to most of the little details that directors like to put in. It often feels like the efforts aren't appreciated by the public because it can be very hard to notice these tiny details.

We love to see when a movie puts in the extra work to make it more interesting and enjoyable. That's why we made this list of some of the hardest to notice details in the Toy Story movies.

1. You can catch a glimpse of a postcard from Carl and Ellie, the lovely couple from the movie Up.

2. The brand name of the batteries powering Buzz is the same company that's putting humans in spaceships and sending robots to Earth in Wall-E.

3. The toolbox Sid places on this crate has the label "Binford Tools". This is the company Tim Allen worked for in the TV series Home Improvement.

4. Mrs. Potato Head is seen reading a book about A Bug's Life in Toy Story 2.

5. The gas station where Buzz and Woody are left behind appears as a sponsor in the Cars movie.

6. Hamm is standing on the board game Clue as he is looking for clues on how to find Woody.

7. The Buzz Lightyear book that Rex is reading has a price of $4.95 in US dollars and $50 in Canadian dollars.

8. The movie A Bug's Life must be very popular in Toy Story 2 as there are toy characters in Al's Toy Barn.

9. The company that made the massive firework Sid bought is called "Ill Eagle Fireworks". Ill eagle.

10. In this scene, you can see that Andy marked the height of Buzz, Rex, and Jesse.

11. When Sid grows up to be a garbage man, his truck's license plate number is RM237. This is a reference to the scary room from The Shining.

12. You might have caught the Jurassic Park reference when Rex was running after his buddies.

13. There's a reference to the movie Alien in one of the games in Pizza Planet with creatures popping out of an astronaut.

14. The man who brings back Woody to mint condition is Geri from Pixar's short film Geri's Game.

15. In a short scene you can see a Lighting McQueen toy in the Butterfly Room in Toy Story 3.

16. Darla from Finding Nemo can be seen on the magazine Molly is reading here.

17. It was a shocking discovery that one of Sid's hybrid toys is actually a hooker.

18. In the movie Monsters Inc., you can see Jesse on the floor of Boo's bedroom.

19. This is also noticeable when he pulls out the drawer full of chess pieces.

20. The stitching that's on Woody's right arm in Toy Story 3 is more apparent because his arm was repaired in the previous movie.

21. The carpet in Sid's house is the same as the one from the Overlook Hotel in The Shining.

22. It's safe to assume that the garbage man in Toy Story 3 is actually Sid.

23. The animators were even aware that Andy's handwriting should improve as he got older.

24. The real estate company selling Andy's house is named Virtual Realty. Brilliant.
