Game of Thrones season 8: HBO boss left speechless by final episodes: 'They are six movies'

'I’ve watched them twice without any CGI and I’m in awe'

HBO boss Richard Plepler has offered a tantalising update on the eighth season of Game of Thrones.

Speaking to Variety at a Golden Globes after-party, Plepler remained coy about specifics, but gave his own verdict on the final six episodes and revealed that each one feels like its own film.

“It’s a spectacle. The guys have done six movies. The reaction I had while watching them was, ‘I’m watching a movie,’” Plepler said.

"[Showrunners David Benioff and D.B. Weiss] knew the bar was high. They’ve exceeded the bar. I’ve watched them twice without any CGI and I’m in awe.

"Everybody’s in for an extraordinary treat of storytelling and of magical, magical production.”

Following the Globes, a new HBO trailer for 2019 was released, featuring a few seconds of previously unseen footage from the upcoming eighth season.

Other shows to feature in the trailer included the premium cable service's new adaptation of Watchman from Damon Lindelof.

The new version of the comic book marks the Lost co-creator's next project since the conclusion of his acclaimed series The Leftovers and stars Jeremy Irons in the lead role.

There is currently no specific release date for the final season of Game of Thrones, although HBO has announced new episodes will start in April. Find out more about season eight here.
