Miranda Richardson, who is set to star in the prequel to the recently concluded Game of Thrones, feels conflicted about the ending of the fantasy drama.

The actor, who currently stars in Good Omens, remains tight-lipped about her role in the prequel, which also stars Naomi Watts. "I can say absolutely nothing except that I'm thrilled and I'm really looking forward to it," she says.

About Game of Thrones, which ended last month, and its highly-divisive finale season, Miranda says, "I have my opinions about certain aspects of it. I'm not unhappy but it all comes down to personal choices in the end."

Meanwhile, the prequel series is set almost a thousand years before the events depicted in Game of Thrones. It will chronicle the world's descent from the Golden Age of Heroes into its darkest hour. From the horrifying secrets of Westeros' history to the true origin of the White Walkers, the mysteries of the East to the Starks of legend, according to the official logline of the show.
