Sudden Impact is a 1983 American  action film and the fourth film in the Dirty Harry series, directed by Clint Eastwood (making it the only Dirty Harry film to be directed by Eastwood himself), and starring Eastwood and Sondra Locke. The film is notable for the catchphrase, "Go ahead, make my day", which is uttered by Clint Eastwood's character in the beginning of the film. That phrase, although in its Italian localization "Coraggio... fatti ammazzare" ("come on, let me kill you"), was also chosen as title for the Italian version of the film.
