Alongside Jenner, the series is hearing from boxer Christy Martin, tennis player Mardy Fish, basketball star Metta Sandiford-Artest and the United Hockey League team Danbury Trashers.

"Sports is a great unifier in our country," directors and co-executive producers Chapman Way and Maclain Way said in a previous statement, per the Associated Press. "It crosses politics. It permeates culture. We've tried to separate it as its own industry, but just like art and film, it's so pervasive it generates a wide discussion amongst people."

"Untold gets to the heart of the passion and single-mindedness it takes to be a champion and the ways in which the triumphs can be undone off the field," Netflix added of the project in a press release.
