Trivia: Cersei remarks to Tyrion that she had heard his nose was cut off during the Battle of Blackwater Bay. This is a reference to the books, in which part of Tyrion's nose was indeed cut off.
Question: Why were so many actors in this show recast? If the showrunners knew they would be using certain characters for multiple seasons, then why not lock them in long term?





Chosen answer: Considering the show was in production for nearly a decade, it is hardly surprising that many characters were recast. Actors constantly move on to other jobs, creating scheduling conflicts. Some may not want to be tied to one project for so long a period, particularly for relatively minor roles that paid little money. As some characters became more prominent, the producers did recast a few roles with better-known actors. For example, Max Von Sydow replaced the actor who originally played the Three-eyed Raven. Some actors voluntarily left for personal reasons. Jennifer Ehle was originally cast to play Catelyn Stark but dropped out because she'd recently given birth. Other actors claimed they were replaced for "political" reasons.
