Los Angeles: US network HBO will make a big screen adaptation of the popular show Game of Thrones when the fantasy drama ends its run on TV, says its creator George RR Martin.

Game of Thrones , which is mainly filmed in Belfast, won several Emmys this year. Speaking at the HBO after party, author Martin said he will not be involved in the film and that show writers David Benioff and DB Weiss will be in charge, reports dailystar.co.uk.

Martin, who is currently writing the final two Game of Thrones books, said: ‘There will be a movie but I will not be involved.

‘I have too much to do. That is something HBO and the DB and David are dealing with. I have two more books to finish and I still have so much to do. The pressure is on. I am such a slow writer and the fans get upset that I don’t write faster.’

A production source said the film may go back in time.

The source said: ‘With the Game of Thrones universe, there is much rich material and no constraints on when that story will take place. They are looking at dipping back in time during certain periods of the series, which could be examined as a one off plot.

‘That means that some of the big characters who fans have seen die on screen could be resurrected such as Robb Stark, Catelyn Stark, Oberyn Martell The Red Viper - and Ned Stark.’

Despite the film plans, Benioff ruled out extending the TV series to 10 seasons.

He said, ‘No way in hell because we know what the end is and we’re rapidly approaching it.’
