'We wrap in December and we air our first episode in April .
British outlet Metro reported last week that Williams said the new season will premiere in April 2019, but she said those quotes were old. After apparently seeing the story circle around with her "quote", Williams took to her Twitter account to clarify that the statement, while not a complete manufacture, is far more accurate. Williams said that there's a four month turn around for these "huge episodes" in the post production phase of development.
It's been known for awhile that there would be a long wait between Game of Thrones season 7 and season 8.
She added: 'There's a lot that goes into the final edit. So, the producers don't want to "rush" anything. We'll explain how to do just that, as well as outline rumours on the Game of Thrones Season 8 release date.
Meanwhile, leaks from the latest season have continued to drop as fans eagerly await the final six episodes.
It comes as HBO boss Casey Bloys admitted the reason for the delay was down to show runners David Benioff and Dan Weiss being "perfectionists".
She slammed the industry's "shallow" nature and believes that casting agents only want a certain "type" of lovely woman.
"I love looking at those totally jaw-droppingly handsome women".
"As the show has gone on, it's gotten bigger - big battle scenes, big special effects".
Maisie went on to call for more diversity in the industry, as she thinks it's a shame that different types of beauty aren't represented. "It's simply a matter of them taking the time they need to execute at the level they feel the fans deserve".
