HBO is working on four possible new TV series which will continue the story from "Game of Thrones," according to The Hollywood Reporter. There are only two seasons left from the famous television production.

Four screenwriters, alongside George R.R. Martin, the author of the novel which inspired 'Game of Thrones', are involved in these potential attempts to extend the universe of the show.

Martin will collaborate with Jane Goldman and Carly Wray on two of these projects, while Max Borenstein and Brian Helgeland will work on the other two ideas.

So far, the subject of these stories is unknown.

If the stories will take place before or after the main narrative of 'Game of Thrones' or if there are an intrigue derived from the main story is also unknown.

Dan Weiss and David Benioff the showrunners of 'Game of Thrones' are not involved in writing these projects, but they will appear as executive producers alongside George R.R. Martin.

When the 7th season of 'Game of Thrones' premiere

The 7th season of 'Game of Thrones'— the most successful television production of the moment— is going to premiere on July 16th this year. With only 7 episodes, the upcoming season is the shortest one so far. The shootings occurred in Northern Ireland, Iceland, and Spain.

Considering the fact that winter is part of the universe of the upcoming season, the production team needed specific climatic conditions to shoot the new episodes, so the premiere —that usually took place in spring — was postponed until summer.

'The Winds of Winter' — which ended the 6th season— is considered the longest episode with nearly 70 minutes and it was broadcast in June last year. It had 8.9 million viewers.

Great success for 'Game of Thrones'

'Game of Thrones' is a television series produced by HBO in the form of a medieval fantasy, based on the novels written by George R.

R. Martin from the series "Song of Ice and Fire." The show presents the dramatic and intriguing adventures involving the members of the Stark, Lannister, Baratheon and Targaryen families who want to conquer the Iron Throne from the Westeros kingdom.

The show has become a true social phenomenon, and is highly appreciated — especially for the actors' performances, for the characters' complexity, for the evolution or the narrative thread, and for the spectacular landscape.

The famous fantasy show has also won many important trophies, including 26 Emmy Awards.

The novels from the series "Ice and Fire Songs" were also sold in more than 60 million copies worldwide and they were translated into 45 languages.
