Due to the prolonged development period of the film, in 2010, DC Entertainment shifted focus onto developing a television series adaptation. Film director James Mangold pitched a series concept to cable channel HBO, whilst consulting with Gaiman himself on an unofficial basis, but this proved to be unsuccessful. It was reported in September 2010 that Warner Bros. Television was licensing the rights to produce a TV series, and that "Supernatural" creator Eric Kripke was their preferred candidate to adapt the saga. In March 2011, it was announced via Neil Gaiman's web blog that while he and DC liked Eric Kripke and his approach, it didn't feel quite right. The author hoped to launch the series in another form but plans for a television adaptation are on hold as production moves forward on the film. As the film adaptation of Morpheus' story was being planned, DC and Fox discussed in September about a possible TV series based on the "Sandman" character Lucifer.
