It was a big day for news of things Game Of Thrones related.  First it was announced the old show runners were off Star Wars.  Then it was announced a prequel was canned.

However this was not the only Game Of Thrones prequel in the works.  HBO have stepped in to clarify that there will still be a prequel to their biggest hit.  The series will debut on HBO’s upcoming streaming service in the US, which launches in May next year and will cost $14.99 a month.

The series – called House Of The Dragon – will begin with 10 episodes and focuses on the House of Targaryen 300 years before the original series. HBO said it would feature:

“…the world’s descent from the golden Age of Heroes into its darkest hour”.

Casting for the prequel has not been announced.  This comes after it was reported that HBO’s first prequel of Game of Thrones, starring Naomi Watts, was no longer happening.

US cable network HBO will be hoping the prequel gives it an advantage as it enters an increasingly competitive market with a streaming war kicking into high gear.
