Based on a true story, The Good Nurse follows Charles Cullen (Redmayne), a nurse who murders dozens – perhaps even hundreds – of patients over the course of a 16-year period. Chastain plays Cullen’s colleague who helped get him arrested, Amy Loughren.
It’s quite a turn for Redmayne who has long played the affable, harebrained wizard Newt Scamander in JK Rowling’s Fantastic Beasts saga, which culminated in The Secrets of Dumbledore this year.
In a new interview with The Los Angeles Times, Redmayne said he relished the opportunity to portray a darker character off the back of the family film series.
“I love making those huge symphonic films,” he said of the Harry Potter spin-offs.
“I love that company of actors – it’s old-school filmmaking of scale. But because of the nature of them, retaining intimacy is hard.”
In contrast, The Good Nurse allowed Redmayne to “mine scenes for everything that they’re worth to try every possible alternative”, he explained.
“That was wonderful. It was delicious. It was what I was dreaming of.”
After the film’s release on Netflix in October, viewers have shared their shock on social media after learning of the morbid true story behind the movie.
The Good Nurse is on Netflix now.
