The Tulsa Race Riot of 1921 is getting the Oprah Winfrey treatment.

Winfrey, leader of OWN: Oprah Winfrey Network, announced Thursday that Oscar winner Octavia Spencer will star in a two-night miniseries based on the Tulsa Race Riot.

 It “is the story of the largest race riot in U.S. history, where over 300 people were believed to have been murdered in Tulsa, Oklahoma – a story that was largely covered up for decades,” according to press information.

The miniseries, which is in development, will center on Mattie Clay (Spencer), a journalist from Tulsa, who moved to Chicago with the hopes of getting off the society pages and away from racism.  Mattie's journey eventually brings her back home to Tulsa where she must face the demons of her past and decide where her future lies.  

"Tulsa" (working title) is being executive produced by Nancy Miller ("Saving Grace").  Co-executive producers are Valerie Woods (“Soul Food”) and Dayna North (“Single Ladies”). No production start has been set.

OWN also announced six-time Grammy-winning artist and actress Toni Braxton will star as Darlene Love in the network’s first scripted TV film “My Name is Love: The Darlene Love Story”  and actor/recording artist Justin Timberlake will kick off a star-studded new season of “Oprah’s Master Class” on May 11.

Also planned are a seven-part event “Belief”  which explores humankind’s search for meaning and connection and Tyler Perry’s popular drama series “The Haves and the Have Nots” and previously announced new series “Single Moms Club” (working title) each have received 20-episode orders.

OWN airs on cable 106 in Tulsa.
