Answer
In the 2007 film Hot Fuzz, Olivia Colman played the role of PC Doris Thatcher. Thatcher is a police officer in the fictional Sandford Police Station in the English countryside. She is a competent officer, but she is also a bit of a prude and a stickler for the rules. She is often at odds with the more relaxed and unorthodox police officers, such as Nicholas Angel (Simon Pegg).
