'Game of Thrones' season 7 production to start laterLos Angeles, July 7(AZINS) Production of the seventh season of "Game of Thrones" will start later, show runner D.B. Weiss has revealed.

Weiss said that they want to capture "grim, grey weather" for the season, reports aceshowbiz.com.

"We are starting a little bit later because, at the end of this season, winter is here, and that means that sunny weather doesn't really serve our purposes any more," Weiss told UFC podcast.

"We kind of pushed everything down the line so we could get some grim, grey weather, even in the sunnier places that we shoot," he added.

As for whether the delay in production would push back the season premiere, Weiss said, "We don't have an air date yet."

HBO has not commented on how the production delay will affect the air date.
