Neil Gaiman has a simple explanation for why he hasn't written Coraline 2 yet.
"I'm waiting for a Coraline [2] story that's as good as or better than Coraline," Gaiman explained, responding to one of his followers on Twitter. "There's no point in making [a sequel that's] less than the first book or movie," he added.
Published by Gaiman in 2002, Coraline is a kids fantasy novel that revolves around Coraline Jones, a young girl who uncovers a secret door in her new home. Upon passing through it, Coraline finds herself in a parallel world nearly identical to the real one, except it's populated by her Other Mother and Other Father -- beings who look just like her real parents, but have black buttons for eyes and cater to Coraline's every whim. In time, however, Coraline learns her Other Mother is actually a dangerous entity who preys on unhappy children, known as the "Beldam," and must find a way to stop her evil plan before it's too late.
Gaiman's book was adapted into the stop-motion animated movie of the same name in 2009, with Dakota Fanning voicing Coraline opposite Robert Bailey Jr. as Wyborne/Wybie, an eccentric young boy who did not appear in the novel but was created for the film. In addition to being a critical and commercial success, Coraline was nominated for Best Animated Feature Film of the Year at the 2010 Academy Awards, losing to Pixar's Up.
Among the other recent titles based on Gaiman's work are the series Good Omens and American Gods, both of which he worked on as, respectively, a showrunner and executive producer. Gaiman is similarly involved with Netflix's The Sandman, a TV adaptation of his landmark dark fantasy comic book property of the same name. Allan Heinberg developed the show, with Gaiman and David S. Goyer serving as co-executive producers.
Netflix revealed several key cast members for The Sandman earlier this year, including Tom Sturridge as Morpheus, AKA Dream of the Endless, and Gwendoline Christie as Lucifer, the fallen angel who rules Hell. Gaiman endorsed the show's cast on Twitter, calling Sturridge "perfect" for the role of Morpheus and teasing "there are many mysteries remaining," as far as the casting of other major characters from the comics are concerned.
