Peter Dinklage: It's the Perfect Time to End 'Game of Thrones' One of Game of Thrones' most beloved actors, Peter Dinklage, is just as sad as you are that the hit HBO show is ending in 2019. “It’s the perfect time to end it. Sometimes shows stay on a little too long, the jumping-the-shark thing. It’s bittersweet when it’s time to move on with everything. It’s always the sad part of our business, because you get pockets of great people for short amounts of time and then you have to move on and it’s always heartbreaking. Fans will find out the fate of those in Westeros during season eight, which will consist of six episodes.
