For Game of Thrones fans who are still dissecting and debating the major developments of season seven after last night's dramatic finale, HBO has released The Game Revealed, a new post-season, behind-the-scenes series available exclusively on HBO NOW, HBO GO, HBO On Demand and affiliate portals. The seven-part series features exclusive interviews with cast and crew that provide new info and insights on how some of the biggest moments from the latest season of the HBO series came together. The first episode of The Game Revealed is now available, and fans can also watch it for free on Facebook and YouTube.

The remaining six episodes will be available exclusively to HBO subscribers, with new episodes rolling out on a weekly basis on subsequent Mondays. The 14-minute first episode, which you can watch below on HBO YouTube, contains previously unseen footage revealing the camera tricks behind Arya's face-changing transformation into Walder Frey, the breathtaking Spanish landscapes that served as the backdrop for Daenerys' home of Dragonstone, and exclusive interviews with episode one director Jeremy Podeswa, prosthetics designer Barrie Gower and cast members, including Emilia Clarke and Maisie Williams, and guest star Ed Sheeran.

Each of these videos will focus on one of the seven episodes, with this episode focusing on the Game of Thrones Season 7 premiere entitled Dragonstone. The video begins with director Jeremy Podeswa explaining that the beginning of each season either starts with something small to "ease your way in," or open with something huge to "get it over with." This season, they opted for the latter, with the opening scene featuring a seemingly resurrected Walder Frey (David Bradley), bringing all of his men back together, praising their work at the Red Wedding, when it was revealed that it was actually Arya Stark (Maisie Williams) using Walder Frey's face, as she poisoned all of the Frey's for killing her brother Robb Stark (Richard Madden). We also hear from Maisie Williams herself, who had this to say about how she was thrilled that they actually made a prosthetic face of David Bradley's Walder Frey for her to wear.

"I was thrilled that they made a full head prosthetic, that fitted my face but I looked like David Bradley. As an actor, to really reveal yourself, and take another face off your face, rather than just pretend, that just made it a lot more easier and fun, I guess. She realizes her power and, I guess yeah, there is the argument that you didn't have to kill the whole Frey army, but they weren't good news. We're not gonna miss them."

The next segment explores the brief scene that showed the Night King and his army marching towards The Wall. We got to see two of the giants in this zombie army that are returning this year, with prosthetics supervisor Barrie Gower revealing that they brought back two returning actors, Ian Whyte and Neill Fingleton, who both got new prosthetics upgrades and costumes this season. We didn't see much of the giants beyond this season premiere, but with the Great War starting up in earnest next season, don't be surprised to see much more of them. This video also delves into the controversial cameo by singer Ed Sheeran, the map room scene in the Red Keep and much, much more. Take a look at the first episode of The Game Revealed as we now start the long wait for the eighth and final season of Game of Thrones.
