The adaptation of Joan Didion's novel is now filming in Puerto Rico and is set for a 2019 release by Netflix. It follows Anne Hathaway's character, journalist Elena McMahon, who finds herself caught up in the Iran Contra Affair.
Rees co-wrote the film with Marco Villalobos.
"Dee Rees is an incredibly talented filmmaker, who continues to make provocative and entertaining films. We are thrilled to continue our relationship with Dee and proud to have her part of the Netflix family," Scott Stuber, head of Netflix's film group, said in a statement when the project was announced in May.
"So proud to be working with my girl Dee again!!! Anne Hathaway, Ben Affleck team up for Joan Didion-based Netflix film," Rodriguez tweeted Tuesday.
