Netflix has released the trailer for its new miniseries, Self Made: Inspired by the Life of Madam C.J. Walker, starring Octavia Spencer.

The four-part limited series tells the exciting story of Madam C.J. Walker, the pioneering black haircare entrepreneur who was America’s first woman to become a self-made millionaire. Pushing back against racial and gender biases and business competition, Walker transformed haircare while championing social change.

The show features Blair Underwood, Tiffany Haddish, Carmen Ejogo, Garrett Morris, Kevin Carroll, and Bill Bellamy. 

Netflix’s project is inspired by the book On Her Own Ground: The Life and Times of Madam C. J. Walker, written by Walker’s great-great-granddaughter A’Lelia Bundles.

Self Made releases on March 20. Watch the trailer above.
