GAME of Thrones producers have been left red-faced after it emerged that rubbish character Samwell Tarly had been kept in the show for eight seasons.

An HBO spokesman apologised and confirmed they would use CGI to remove him once the series has finally come to an end.

Eagle-eyed fans spotted the pointless oaf during a season eight episode, before going back and realising he had been there the whole time.

Many viewers are asking how it could happen in a prestige production, while others complained of being taken away from an engaging story featuring multi-dimensional characters.

Thrones fan Emma Bradford said: “I could hear an annoying noise so I adjusted my TV volume. It was then that I realised that gormless yokel Samwell Tarley had been left in shot.

“It’s a massive embarrassment for the show, and it almost ruined this season for me. The only way they can make it up is if they fling him out of a trebuchet and into a wall in the next episode.”
