If you leave and breathe nothing but Game of Thrones, you've likely soaked up every possible scrap of information about the show over its successful run on HBO. But if you're a more casual viewer who just loves the show but hasn't spent countless hours digging into how it came to be or other interesting trivia, this video from The Film Theorists is for you.
The video takes us through the early days of the show's development, revealing how showrunners Benioff and Weiss were able to secure the rights to George R.R. Martin's novels even though Hollywood had been rabidly clamoring for them for years. It gets into some alternate casting from the pilot (which I'd never bothered to learn about myself), and then proceeds into some trivia about some of the cameo appearances on the show over the years. Overall, it's a good place to start for those looking to dive a little deeper into one of the most popular shows on television.
