James Norton seen filming at Leavesden Studios in leaked video
Happy Valley actor James Norton has been spotted in Watford filming scenes for House of the Dragon.
A leaked video from the set of the Game of Thrones prequel at Warner Bros. Studios Leavesden shows the 40-year-old acting alongside Matt Smith's Daemon Targaryen.
A child actor, who appears to be playing a member of the Targaryen family due to his white hair, also features in the clip which has made the rounds online and been shared by Splash News.

In January, it was announced that the Happy Valley and Grantchester star had been cast as Ormund Hightower, who is a major lord and the cousin of Oliva Cooke's character Alicent.
Filming for the third series started at the studio off Aerodrome Way in March, according to Comic Basics, and is apparently set to continue there until series is then expected to be released via Sky Atlantic in the UK next year.
House of the Dragon is based on George RR Martin's 2018 book Fire & Blood and is set before the A Song of Ice and Fire books, which formed the basis of Game of Thrones.
Previous series of the HBO show were also filmed in Leavesden and this summer it is joined by the broadcaster's Harry Potter TV adaption, which began production last week.
