Meet the New Cast of The Crown Season Four

The Role: At the end of the 1970s, Prince Charles, heir to the British throne, was in want of a wife. Lady Diana Spencer—later Princess Diana—was just the young woman for the job, or so the royal family believed. Diana was thrust into the spotlight at just 19 years old; her incredibly complex entry into royal life plays out over the course of season four of The Crown.

The Actor: Emma Corrin is a relative newcomer. At just 24, this will be Corrin's first major role, though her previous credits include the Epix Batman spinoff Pennyworth.
