NBC has given a series order to the Oz-themed “Emerald City,” which is said to be a dark and modern take on “The Wonderful Wizard of Oz,” along the lines of HBO’s “Game of Thrones,” reports Deadline.com.

The drama will go to the source material for the Oz tale, the 14 books written by L. Frank Baum. The stories include “lethal warriors, competing kingdoms, and the infamous wizard as we’ve never seen him before,” the piece notes.

NBC has given the series a 10-episode order. It comes from “Siberia” creator and showrunner Matthew Arnold and features a 20-year-old Dorothy Gale as she gets involved with an epic battle for control of Oz, the piece says.

While a writer’s room is expected to be set up soon, casting may be postponed until after pilot season, the article adds.

“Emerald City” is the first of several "Wizard of Oz"-themed projects in development at different networks to receive a series order.

NBC has also greenlighted a drama pilot starring “Grey’s Anatomy” actress Katherine Heigl, called “State of Affairs.” The drama stars Heigl as a CIA attache who counsels the president and also has to deal with a complicated personal life.
