One of two eagerly awaited prequels to the hit HBO series Game of Thrones has been scrapped, according to an Entertainment Weekly report. From showrunner Jane Goldman (Kick-Ass), the new series starring Naomi Watts was set to take place thousands of years before the events of the original series. Against the backdrop of The Long Night war with the the White Walkers, the project planned to explore issues of race and power. It has been in the works since June 2018 and filmed a full pilot over the summer before the network pulled the plug. Though Goldman has reportedly been emailing the cast and crew about the cancellation, it has yet to be confirmed by HBO.

Another Thrones prequel created by Ryan Condal (Colony) and author George R.R. Martin is still in the works, and Variety reported later Tuesday that it will be streamed on HBO. The House of the Dragon series, which was given a 10-episode order, will tell the tale of House Targaryen and is supposed to take place about 300 years before the events of the original series. Miguel Sapochnik, a frequent director for Game of Thrones, will reportedly direct the pilot and additional episodes.
