Passage: In October 2010, Walt Disney Pictures retained the film rights for the 1962 novel A Wrinkle in Time, by Madeleine L'Engle, which had previously been made as a 2003 television film. Following the financial success of Tim Burton's Alice in Wonderland (2010), Disney hired Jeff Stockwell to write the screenplay for Cary Granat and his new Bedrock Studios. Granat had previously worked with Disney on the Chronicles of Narnia and Bridge to Terabithia films. The project's budget was slated to be $35 million, which the company compared to "District 9 and Bridge to Terabithia," both of which were made for less than $30 million. However, A Wrinkle in Time was part of a new California Film Commission tax credit program, which offset production costs considerably. On August 5, 2014, Jennifer Lee was announced as the screenwriter, taking over from Stockwell, who wrote the first draft. On February 8, 2016, it was reported that Ava DuVernay had been offered the job of directing the film, and she was confirmed to direct later that same month. She became the first non white woman to direct a live-action film with a production budget of more than $100 million. The decision received positive sentiments in the media industry. Oprah Winfrey was happy to see this because DuVernay herself broke barriers for non white people in the film industry. "So I do imagine, to be a brown-skinned girl of any race throughout the world, looking up on that screen and seeing Storm, I think that is a capital A, capital W, E, some, AWESOME, experience." Irene Monroe of The Cambridge Day expressed her feelings that Ava DuVernay was a superb choice of a director, due to the fact that she was able to correctly highlight and expose the struggles experienced by young African-American girls.
