Nearly two years after Game of Thrones aired its final season, HBO and HBO Max chief content officer Casey Bloys has presented some new details about the future of the series.

Deadline reports the show's upcoming prequel sage, "House of the Dragon," is set to begin production this April, but more spin-off series are apparently in the works at HBO.

I'd rather get scripts good and make them stories worth telling than shoot for a certain number of shows. Bloys told Deadline. 

The prequel series is just one of apparently five different prequel ideas in the works, one being focused on George R.R. Martin's "Tales of Dunk and Egg," which is set in the same world.

There is also an animated GoT series in the works according to recent rumors.

Bloys says he does not have an exact number in mind when it comes to the amount of potential GoT spin-off series. 

"I don’t necessarily have a number in mind but the goal is always the same which is, let’s get in business with people we believe in and shows that we believe in and worry about the rest later," said Bloys.

Bloys also discussed the future of HBO's other smash hit, "True Detective," which has not aired a new season since 2019.

He says they're still looking for the right "tone." 

"It’s safe to say we’re working with a couple of writers to find the right tone and take,” he said, "It’s definitely an area that could be very interesting and I think it would be interesting with a new voice."
