3. Sophie cried at the read-through for the final season, but said she didn't cry as much as Kit!
4. Maisie Williams (Arya Stark) remembers that her first day on set involved acting in the scene where she flicks pigeon pie at Sansa, and they kept telling her to aim better.

6. Liam Cunningham (Ser Davos) walked away from the show with a Dothraki sword and the stag that he gives Shireen.
7. Nikolaj Coster-Waldau did not get to keep Jaime's hand after wrapping — even though he said it was the one thing he wanted.
8. The very first scene Kit Harington (Jon Snow) filmed was when he was walking down the ramparts, but his favorite part of shooting the entire series was filming the scene where he was unable to behead Ygritte in Iceland during Season 2.
9. Kit said he wasn't embarrassed when he had to act dead on a table during the first two episodes of Season 6. In fact, he said it was VERY easy and he even fell asleep a few times.
10. Gwendoline Christie (Brienne of Tarth) was always mentally prepared for her character to die every time she went into a new season.
11. It took Gwendoline a long time to digest the storyline for Season 8, but she thinks they did a good job.
12. Gwendoline said that playing the part of Brienne changed the way she walked after four months of shooting, and that her costume was often "very intense and very painful."
13. Sophie's fiancé, Joe Jonas, was on set for most of the final season. So not only did he figure out the ending, but they made him sign an NDA.

17. Emilia has FOUR wigs she uses when playing Mother of Dragons — and they all have names! Dany, Diva, Candice, and Blondie.
18. Lena Headey calls her short Cersei wig "the Turnip."
19. At the beginning of the show, Emilia only had one wig. That had to change over the years because the wig would get dirty and ruined when shooting some scenes, especially ones with smoke/fire.
20. During Cersei's walk of shame in Season 6, the styling team had to have 10 wigs prepared — 5 for Lena Headey, and 5 for her double.
21. Sophie said that basically everyone on the show wears a wig, and even some of the men have beard inserts to make facial hair look less patchy.
22. A few years into filming, Sophie had to start wearing wigs after she damaged her hair by going from red to blonde.
23. In Season 6, Maisie was required to wear blind contact lenses, which she said were very thick and painful. She also could not see out of them.
24. The sounds the dragons make were inspired by the noises tortoises make while mating.
25. A crane with a 15-foot-high arm and a flamethrower mounted to it was used for the dragon fire. It could shoot as far as 50 feet and was programmed to follow Drogon's movements.
26. Queen Elizabeth visited the set of Game of Thrones, but according to David Benioff, she didn't sit on the fictional throne because "the Queen of England is not allowed to sit on a foreign throne."

31. Dragonglass is made from obsidian, but the weapons created for the show were 99% rubber.
32. According to a 2017 report from Money.com, Game of Thrones cost $10 million per episode, about the same amount per episode as the final season of Friends — though the latter was less about production value and more because all six members of the main ensemble received $1 million per episode.
33. For the final season, the cast had to download an app in order to get the script. Once they finished the script, it would magically disappear — like on Snapchat. (Also, the app doesn't allow users to take screenshots!)
34. Showrunner Dan Weiss said that the creators have known the final major beats for the ending of the show for the last five years.
35. Sophie was the first one to finish reading the scripts for the final season and the first one to write to David and Dan about it.
36. Kit found out the ending of the last season during the final table read, because he had decided not to read the script ahead of time.
37. David and Dan weren't aware that Kit was going to wait until the official table read to read the script for the first time, so they initially thought his failure to communicate his thoughts with them was because he hated the script.
38. At one point during filming the last season, Dan and David had taken the precaution to set up giant shipping containers on the street so that nobody could see what they were filming, but a concert came into town and set up a Ferris wheel — so that plan ended up being a massive fail.

40. Showrunners Dan Weiss and David Benioff directed the finale of the series.
41. HBO was more than happy to grant them more episodes, but Dan and David knew deep down that Season 8 is where the story is meant to end.
42. After the finale airs, Dan said that he "plans to be very drunk and very far from the internet." (AHHH, so many possibilities as to what this could mean!)
43. They've come a long way since they shot the original pilot — nope, not the one you've seen in Season 1. There was a whole OTHER pilot.
44. Dan referred to showing the pilot to people for opinions as "one of the most painful experiences of my life." David said that while taking notes, he remembers writing in all caps, "MASSIVE PROBLEM."
45. One of the original pilot's major issues was that it wasn't clear Jaime and Cersei were brother and sister. David said that is "a major, major plot point that we had somehow failed to establish."
46. Dan and David recall Sophie and Maisie "hugging each other and bawling" at the pilot's wrap party because they were afraid the show wouldn't get picked up, and they'd grown really close as friends in a short amount of time.
47. The showrunners ended up recasting and reshooting 90% of it.
48. Nikolaj Coster-Waldau called the first pilot "unbelievably bad."
49. The roles of Daenerys and Catelyn Stark were recast when the showrunners reshot the pilot.
50. Sean Bean (Ned Stark) and Peter Dinklage (Tyrion Lannister) never had to audition; instead they were chosen to play their roles.

69. Hannah had worked with Joe Dempsie (who plays Gendry) during her first job, which was the show Skins.
70. Sophie said that her favorite day on set was when Arya was reunited with Sansa, saying it was both "funny and difficult" because they couldn't keep it together.
71. Maisie said it was kind of awkward reuniting with Sansa onscreen because it was a bit strange having to act in front of each other again after acting apart for so long.

98. George R.R. Martin's earliest memory of a fantasy story is when he owned dime store turtles when he was little.

That's when he imagined they were fighting over a "turtle throne."
