The original series "Game of Thrones" is inching towards its end but the saga is expected to continue. George R.R. Martin, the author of the "A Song of Ice & Fire" saga, on which the series is based, wrote in a blog post that three spin-offs are "still moving forward nicely".

"The one I am not supposed to call 'The long night' will be shooting later this year," he wrote on Saturday, reports variety.com.
