The show, orginally created as a television movie, was retooled as a mini-series for ABC's Thursday night slot in place of Scandal, which was delayed to midseason due to Kerry Washington's pregnancy.
The lead characters are based on real-life criminal defense attorney Mark Geragos and Larry King Live news producer Wendy Walker.
It's inspired by true-life stories.
Both lead actors previously starred in USA Network series that were cancelled in 2015. Piper Perabo starred in Covert Affairs, which ended after its fifth season. Daniel Sunjata starred in Graceland, which ended after its third.
