The eighth season has yet to begin shooting yet but Mr Weiss and Mr Benioff have begun writing it.
The channel doesn’t have a timeline for the development of the potential spin-off projects but has writers from several major movies and television series on board.
The executive producers of the original series, Dan Weiss and David Benioff, will be involved with the four spin-off projects but won’t be writing any of them.
Games of Thrones spin-offs are coming as US broadcaster HBO has closed on deals with four writers to explore additional shows for the most popular series in its history.
