Contrary to the demented Viserys that Game of Thrones fans know from the first season of the parent show played by Harry Lloyd, this Viserys is a kind and decent man… but not necessarily a great king.
Paddy Considine will play King Viserys Targaryen for House of the Dragon, according to Deadline.
While other Targaryen monarchs were chosen exclusively by the line of succession via blood, Viserys I was chosen by the lords of Westeros to succeed the previous king.
