A new GAME OF THRONES spin off show, A KNIGHT OF THE SEVEN KINGDOMS, will begin filming at Titanic Studios in the next few weeks with author George RR Martin expected to make a visit to the site in July. The author confirmed in a blog post that three seasons have been written for the upcoming series, although they will be shorter than both GAME OF THRONES and HOUSE OF THE DRAGON. The show will debut in 2025, with actor Peter Claffey cast as lead character, Ser Duncan.
