Now, she's back in another true-crime series, "The Act" on Hulu, which tells the complicated and shocking story of Dee Dee Blanchard and her daughter, Gypsy Rose. Dee Dee allegedly suffered from Munchausen by proxy syndrome, a mental illness where a caregiver purposely causes harm or illness to another personand Joey King, who plays Gypsy. Their chemistry was immediate, Arquette told us. "It was really weird, Joey and I just kinda had that chemistry the whole time. I felt like she was my daughter. We have the same sense of humor." 
It wasn't easy to find someone to play the role of Gypsy; one of the series' executive producers/writers, Nick Antosca said it took a long time to find King. "We auditioned a million girls for Gypsy and then we saw Joey," he told us. "He said he specifically had Arquette in mind for the project."
