Yes, 'The Good Nurse' is based on a true story. The cast includes Eddie Redmayne and Jessica Chastain. They both did an amazing job bringing the story to life. Eddie Redmayne was particularly good at portraying the complex character he played.
The true story itself inspired the casting. Since it was such a complex and disturbing real - life event, they needed great actors. Eddie Redmayne was chosen for his ability to play complex characters, and Jessica Chastain for her strong acting skills to handle a role of a nurse who uncovers the truth.
The main character in the true story was Charles Cullen, a nurse who was later revealed to be a serial killer. He worked in various hospitals and was involved in the deaths of many patients.
Compassion. In a true story, a good nurse always shows compassion towards patients. They understand the patients' pain and fear, and try to comfort them, just like the nurse who held a crying child patient until the child felt better.
