HBO Is Preparing For Multiple 'Game Of Thrones' Prequels

During season one, HBO was already spending an average of $6 million per episode on Game of Thrones. Now the series is reaching its final six episodes, but the network is also planning on going big for the prequels. There are currently five Thrones prequels in development. HBO prefers to call them “successor shows." Creator George R.R. Martin is reportedly working with all of them in some capacity.
