Jessica Chastain, Eddie Redmayne aim for utter authenticity in true-crime saga ‘Good Nurse’

“The Good Nurse” tells the true story of Charles Cullen, a seemingly empathetic New Jersey nurse who was later revealed to be a serial killer. No matter how dark the material — and no matter how hard it was to align their schedules — Eddie Redmayne and Jessica Chastain wouldn’t let “The Good Nurse” go. “I don’t know that in Hollywood that a movie’s been around for six years and all the main players stayed on and no one got replaced or abandoned ship,” Chastain says proudly. It’s crazy that this woman who needed a heart transplant has the biggest heart in the world.” “The Good Nurse” is ostensibly a thriller, but Lindholm fought the clichés of the serial-killer genre, leaving Charles Cullen’s motivations intentionally opaque — a decision Redmayne found riveting. “The traumatized 7-year-old was something that I tried to just make sure was in me in all moments.” Eventually, though, Charlie will explode, the character’s ugliness spewing out in the film’s final sequences.
