'Game of Thrones' announces behind-the-scenes doc to air week after finale

Those tight-lipped Game of Thrones creators are finally ready to spill their secrets.

Announced today by HBO, Game of Thrones: The Last Watch is an upcoming documentary that aims to give fans a behind-the-scenes look at the making of Season 8, produced by the people behind it -- and the rest of the monumentally successful series.

Set to air on May 26, a week after Thrones' final episode, The Last Watch will capture in just two hours what it was like for the cast and crew of the series to bring the 8-year franchise (and all of on-screen Westeros) to an end.

The doc is headed up by acclaimed filmmaker Jeanie Finlay, who was "embedded on the set" for a year to capture what it took to create the grand finale.

Contending with "extreme weather, punishing deadlines and an ever-excited fandom," the people behind the biggest show on television faced an uphill battle when it came to delivering a hype-worthy conclusion. Whether they pull it off remains to be seen, but The Last Watch should give viewers a good idea of what a challenge the cast and crew faced.

Game of Thrones: The Last Watch airs on HBO Sunday, May 26 9 p.m. ET.
