A deal to bring Gaiman's beloved Vertigo comic book series The Sandman to the small screen is close to happening. "More than three years after New Line's failed attempt to turn the graphic novel into a feature film, Netflix has signed what sources describe as a massive financial deal with Warner Bros. Television to adapt the best-seller into a live-action TV series," according to The Hollywood Reporter's Lesley Goldberg. "Sources familiar with the pact note it is the most expensive TV series that DC Entertainment has ever done." Gaiman discussed the possibility of a Sandman TV series in March while promoting Good Omens. (A Sandman series was pitched to HBO in 2010.) The potential series will be written by Allan Heinberg with Gaiman and David S. Goyer serving as executive producers after being attached to the movie adaptation. It's been a long road bringing Sandman to the screen -- a Sandman movie has been in the works since the 1990s. According to Goldberg, "the Netflix take represents the first Sandman TV series after numerous efforts to adapt Gaiman's horror, fantasy and mythology tale about Morpheus, the Lord of Dreams, and the Endless, the powerful group of siblings that includes Destiny, Death, Destruction, Despair, Desire and Delirium (as well as Dream)."
