Fantasy drama TV series "Game of Thrones" won't be getting a prequel series, it's executive producer has said.

With only two seasons left for the hit TV series, fans have been asking whether or not there would be any chance of spin-off set in the past.

Executive producer of the show, David Benioff, has now answered the question, saying "this is it" and they won't be making anything else once the final two seasons have aired, reports femalfirst.co.uk.

"You might want to ask George (R.R. Martin) about that. It's a great world that George created. I think it's a very rich world, and I'm sure there will be other series set in Westeros, but for us, this is it. That's really a question for George," Benioff said here.

Author of the novels by the same name, George R.R. Martin won't be quitting the "Game of Thrones" world any time soon, and has shared that fans of the series can still enjoy new material in written form.

"Well, I do have thousands of pages of fake history, everything that led up to 'Game of Thrones', so there's a wealth of material there, and I'm still writing more. At the moment, we still have this show to finish, and I still have two books to finish, so that's all speculation," Martin said.

The news comes after the hit series bagged 12 of the 24 Emmys it was nominated for.
