"This is strange," said Game of Thrones [1] co-creator D. B. Weiss at the start of the seminal show's final table read. "It's like looking around and seeing your family." The making of the final season [2] of the groundbreaking HBO hit is the subject of the forthcoming documentary [3], Game of Thrones: The Last Watch, by British filmmaker Jeanie Finlay.

In the recently released trailer, it's made clear how much careful planning, creativity, and heart went into those last six episodes. It's especially fascinating given how famously secretive cast and crew have been over the years, so as to avoid divulging any spoilers. In the two-hour documentary coming to HBO on May 26, it looks like they're finally laying it all out. Watch the exciting and emotional trailer above.
