Update: Reps for Chastain tell E! News that she will not be in the series.
Here's an interesting bit of grist for the rumor mill: Nerdist is reporting that Jessica Chastain has been offered a lead role in True Detective's second season. Chastain's reps declined to comment, but the casting would would make sense; the Zero Dark Thirty Star already has plenty of experience hunting bad guys and being a lone wolf/loose cannon who defies official government protocol. No word on her ability to philosophize grimly about the futility of human existence, but maybe her Interstellar co-star Matthew McConaughey can give her some pointers?
