Ratchet
The examples we have seen so far are lovable heroines, but not all nurses have kind hearts. That is the case for nurse Ratchet who first appeared in the 1975 film by Miloš Forman One Flew Over the Cuckoo’s Nest.
This character, played by Louise Fletcher, is one of the most famous villains in cinema history. For her performance in this film, Fletcher won an Academy Award. In 2020, a prequel series called Ratched premiered, starring Sarah Paulson.
