Sudden Impact

''Sudden Impact'' is a 1983 American neo-noir action thriller film, the fourth in the ''Dirty Harry'' series, directed, produced by and starring Clint Eastwood (making it the only ''Dirty Harry'' film to be directed by Eastwood himself) and co-starring Sondra Locke. The film tells the story of a gang rape victim (Locke) who decides to seek revenge on her rapists 10 years after the attack by killing them one by one. Inspector Callahan (Eastwood), famous for his unconventional and often brutal crime-fighting tactics, is tasked with tracking down the serial killer.

The film is notable for the catchphrase "Go ahead, make my day", written by John Milius and uttered by Clint Eastwood's gun-wielding character in the beginning of the film as he stares down an armed robber who is holding a hostage. This is the last ''Dirty Harry'' film to feature Albert Popwell. Provided by Wikipedia
