'Game of Thrones' Prequel: Release Date, Title, Trailer, Plot, and Cast

Game of Thrones may be ending in 2019, but HBO has plans to leave the world of Westeros that author George R.R. Martin created for us more than 20 years ago. HBO has already ordered a Game of Thrones prequel set long before the current story ever began. But how long will fans have to wait to see this potential series? What story will this new series tell? Who has been cast?

Here’s everything we know about the upcoming Game of Thrones prequel on HBO, from a possible release date to the confirmed series title and cast members.

When Is the Game of Thrones Prequel Release Date?

An exact release date is unknown. Principal photography for the prequel pilot began in early May 2019 in Belfast, Ireland, according to The Sun. Some outlets claim the pilot will air on HBO in summer 2019, but that’s an extremely tall order by any standard. If anything, the prequel pilot will arrive on HBO in late 2019 at the earliest, but could more likely arrive in spring or summer 2020, once the dust on Game of Thrones has settled.

This information was seemingly confirmed by HBO programming president Casey Bloys in 2017. Reported via The Hollywood Reporter, Bloys commented, “My guess is it would be at least a year before you saw anything else” after the final season of Game of Thrones. What I don’t want is the attention to be drawn from the final season, which I think is going to be epic and amazing, and somehow have the distraction of a new Game of Thrones airing right after that. It’s best to separate it and that’s what we’ll do.”

Kit Harington, who plays Jon Snow on the Game of Thrones, has already voiced his excitement for the prequel, telling Variety he thinks the “balls out” nature and “bigger” budget of the final season will “establish that HBO can do this” with GoT possibly expanding with a prequel. Richard Pepler, who is exiting as HBO’s CEO, called the prequel “something special,” with “a fresh, exciting perspective that didn’t let the franchise go away,” in the same interview.

However, the new HBO boss Bob Greenblatt seems a bit more hesitant about GoT spinoffs. “I think to figure out a way to sustain Game of Thrones or the Game of Thrones world for the future is a really good idea — if it makes sense creatively and if everybody is on board,” he said to The Wrap. “Because the last thing you want to do is roll out a spinoff or two and they’re not up to the standard of the original show and then you’ve just sort of failed miserably.”

“Can you really do two spinoffs? I don’t know,” Greenblatt said. “I’m not even sure you can do one.”

When Will the Game of Thrones Prequel Trailer Be Released?

Again, this is all assuming HBO orders the prequel to series. However, if it does, it’s likely that fans will see a teaser or two before an official trailer.

It will all depend on how secretive HBO decides to be about a Game of Thrones prequel. The level of security likely won’t be as high as it is for the final season, but that doesn’t mean we’ll necessarily get too much footage too early on. With production not slated to start until the summer, we shouldn’t expect anything soon.

In all likelihood, a teaser will probably arrive during a major television event like the Super Bowl. The 2019 Super Bowl featured a commercial previewing all of the new and returning series for the 2019 TV season, including the final season of Game of Thrones. A similar move is possible with production already begun on the prequel since it’s like there will be enough footage to include in a commercial in early 2020.

What Is the Game of Thrones Prequel’s Actual Title?

The Evening Standard reported on Wednesday, April 14 that the new working title for the prequel series is Bloodmoon. A source speaking with ES shared that “those working on the set in Belfast are referring to the series as Bloodmoon. Producers have put together a stellar cast and it will be must-watch telly for anyone who loves Game of Thrones.”

HBO hasn’t officially commented on whether or not Bloodmoon will remain the title of the series. It’s also unclear how the title Bloodmoon ties into the A Song of Ice and Fire novels. Blood magic is an obvious first thought since it’s been seen on Game of Thrones via Melisandre. Similarly, mention of a red star that bleeds is part of the Azor Ahai prophecy, but the moon isn’t a star — unless astronomy works differently in Westeros. We may just have to wait until the pilot airs to see if the meaning behind the title is explained.

Previously, GRRM teased that he thought the prequel would be called The Long Night, but we now know that’s not the case. At the time, he said on his blog in November 2018: “HBO has informed me that the Jane Goldman pilot is not (yet) titled THE LONG NIGHT. That’s certainly the title I prefer, but for the moment the pilot is still officially UNTITLED.”

Here are two parts of 'Game of Thrones' that won't be in a potential prequel series.

What Is the Game of Thrones Prequel Plot?

HBO hasn’t revealed much about the prequel, but it has released a description.

Taking place thousands of years before the events of Game of Thrones, the series chronicles the world’s descent from the golden Age of Heroes into its darkest hour. From the horrifying secrets of Westeros’s history to the true origin of the White Walkers, the mysteries of the East to the Starks of legend, only one thing is for sure: It’s not the story we think we know.

Martin narrowed down the timeline a bit more and gave a few more details in an interview with Entertainment Weekly. “It’s closer to 5,000 years,” he said. “Westeros is a very different place. There’s no King’s Landing. There’s no Iron Throne. There are no Targaryens — Valyria has hardly begun to rise yet with its dragons and the great empire that it built.”

Who Is in the Game of Thrones Prequel Cast?

Naomi Watts will star as “a charismatic socialite hiding a dark secret,” according to HBO.

The prequel has also cast Miranda Richardson as what will be a series regular if HBO orders it to series, Entertainment Weekly reported.

The rest of the cast includes Josh Whitehouse, Naomi Ackie, Denise Gough, Jamie Campbell Bower, Sheila Atim, Ivanno Jeremiah, Georgie Henley, Alex Sharp, and Toby Regbo. However, no details about any of their characters have been revealed.

Who Is Part of the Game of Thrones Prequel Crew?

Jane Goldman created the prequel alongside original author Martin. Goldman will also serve as series showrunner.

Goldman, Martin, SJ Clarkson, James Farrell, Jim Danger Gray, Vince Gerardis, Daniel Zelman, and Chris Symes will all serve as executive producers.

Clarkson will also direct the pilot. She previously worked on The Defenders and Jessica Jones and will direct the next Star Trek film.
