Eastwood directed and starred in the fourth "Dirty Harry" film, "Sudden Impact", which was shot in the spring and summer of 1983 and released that December. It is considered the darkest and most violent of the series. By this time, Eastwood received 60 percent of all profits from films he starred in and directed, with the rest going to the studio. "Sudden Impact" was his final on-screen collaboration with Locke. She plays an artist who, along with her sister, was gang-raped a decade before the story takes place and seeks revenge for her sister's now-vegetative state by systematically murdering the rapists. The line "Go ahead, make my day" (uttered by Eastwood during an early scene in a coffee shop) has been cited as one of cinema's immortal lines. It was quoted by President Ronald Reagan in a speech to Congress, and used during the 1984 presidential elections. The film was the second most commercially successful of the "Dirty Harry" films, after "The Enforcer", earning $70 million. It received very positive reviews, with many critics praising the feminist aspects of the film through its explorations of the physical and psychological consequences of rape.
