Game Of Thrones: Casting House Forrester From The Telltale Series

In Telltale's video game, Ryon Forrester, the house's youngest son, is little more than a plot device. To be more specific, he's the character who exists solely to be kidnapped and used as a bargaining chip. That said, he does still have his brief moments in the sun, specifically when sticking it to his family's enemies and kidnappers, House Whitehill.

In any case, if the child were to be portrayed in the show, the young Liverpool native Nathan Mack would likely be the safest bet.

In addition to being right around Ryon's age, Mack has a couple of semi-decent performances under his belt, such as Tyler in the television drama Babylon and, more recently, Chip Potts in 2017's Beauty and the Beast.

True, that's not exactly the most impressive résumé for a child actor, but the fact remains that he has experience, as well as formal training in the craft. Plus, as stated before, Ryon's role in House Forrester is a relatively small one and Mack is close enough to him in both age and looks, so he would still be a solid choice.
