Due to this series taking place across the span of many years, to best demonstrate the characters’ growth, the younger Targaryens actors will be replaced with older actors. Milly Alcock, who played Rhaenyra Targaryen, is set to be recast by Emma D’Arcy. Alicent Hightower, who was played by Emily Carey, will be recast by Olivia Cooke.
According to show’s creators, the characters who initially cast as children will be the ones subject to this recast, whereas those who were already adults will appear aged with makeup and silvered hair.
This will be a fascinating development to observe. So stay tuned to find out what happens from here!
