The horror writer released a sci-fi title, "11/22/63," this year as well as a new title in his "Dark Tower" series, and he's due to publish a novel, "Joyland," as well as a sequel to his classic novel, "The Shining." Multiple adaptations of his works – including a TV or feature film version of "The Dark Tower" that has languished in development – are planned. King most likely took in $39 million this year, said Forbes.
