The writing for a show can only be so good if it’s delivered properly. Obviously, the cast plays a big part in making a show truly great, and HBO’sHouse of the Dragonis no exception.
Each cast member is able to bring their own uniqueness to a production, allowing for every character to come to life from the page to the screen. While the actors can show versatility within a single project, viewers can really appreciate their talent when they separate them from any single role, and see them perform in different movies or TV shows. Some of the best actors from the HBO series have such a diverse catalog that fans may enjoy seeing them in outside of Westeros.
