It's pretty clear from watching just a few minutes of "Game of Thrones" that a lot of work goes into the show, from the writing to the shooting process to the completed episodes.
But how exactly did the epic TV adaptation of George R.R. Martin's "Game of Thrones" come to be? The story is a long one, much like the immense history of the Seven Kingdoms, but a new video from HBO sums the fascinating tale up in just five minutes. One of the craziest parts of the story is how series creators Dan Weiss and David Benioff ran into a massive problem with the "Game of Thrones" pilot when they realized they left out tons of crucial information.
Besides the history of the show, the video -- which is narrated by Charles Dance, aka Tywin Lannister -- also sheds some mind-blowing facts about the series. For instance, did you know just one season of "Game of Thrones" includes 100 locations, 3,000 costumes, 4,000 props, and 257 cast members? You won't even guess how many visual effects frames are needed for just 10 episodes.
Whether you're a true "GoT" fan or you just want to impress your friends, this video is a must-see, and it will hold you over until the Season 4 premiere.
"Game of Thrones" Season 4 premieres on HBO on April 4.
