Shailene Woodley was seriously thinking of quitting acting and had been refusing scripts for a year before this one came her way and she fell in love with the character of Jane. A phone call of encouragement from her friend and co-star Laura Dern solidified her decision to take the role.
Alexander Skarsgård said that the therapy sessions between Perry and Celeste were filmed without rehearsal, and he appreciated that, since accordingly he and Nicole Kidman had genuine tension and awkwardness having to read the other's emotions in the scene.
Nicole Kidman and Reese Witherspoon each earn $1 million an episode for the sequel series. That's a significant bump from the reported range of $250,000 to $350,000 the pair made per episode during season one.

In order to work on the first season, Reese Witherspoon backed out of Pequena Grande Vida (2017), while Nicole Kidman turned down a part in Mulher-Maravilha (2017), both because of scheduling conflicts.
