Sarah Snook on Portraying Trauma
Besides starring, Snook also serves as an executive producer. She shared insights during a press conference about the challenges of depicting such intense emotional turmoil authentically.
“It is high drama, but like getting into this hysterical, histrionic overreacting … like finding the kernel of truth in these things. Like, ‘What is it like to have your child go missing? What is that like?’ For this person like that, that was the hardest thing to constantly make sure that we were delving down into what is the truthful version of this.”
Snook also revealed her method to keep the emotions genuine:
“We’re during the first read through and I write on the first page: ‘Must find different ways to cry.’ Because I was crying all the time, dealing with what’s happening. Finding different levels of like, ‘Okay, this is level 10.'”
