* AFIS100Years100Thrills: #41
** #17 Hero, Harry Callahan
** #51, "You've got to ask yourself one question: 'Do I feel lucky?' Well, do ya, punk?"
* BeamMeUpScotty: The line is "Do ''I'' feel lucky?", not "Do ''you'' feel lucky?".
** Nor is it "Do ya feel lucky, punk?" (although that is what Eastwood said in the second film).
* CompletelyDifferentTitle: ''(The) Inspector Harry'' in a few countries, ''Inspector Callaghan: The Scorpio Case Is Yours'' in Italy, ''Dirty Cop'' in Dutch, ''Implacable Pursuer'' in Brazil, and ''The Fury of Reason'' in Portugal.
* DawsonCasting: Debralee Scott, the uncredited actress playing the (nude) 14 year old girl, was (thankfully) 18.
* DuelingMovies: The first film with ''TheFrenchConnection'', another 1971 CowboyCop movie.
* FountainOfExpies: Harry, being the TropeCodifier for the CowboyCop, is the starting point for many AntiHero police characters.
* RealLifeRelative: In the first movie, at the quarry scene in the end, Andy Robinson is taking his own stepson Steve Zachs hostage.
* TheRedStapler: Sales of Harry's iconic Smith & Wesson Model 29 [[IncrediblyLamePun shot through the roof]] after the movie's release.
** Specifically, Smith & Wesson stopped producing the Model 29 several years before the film's production. Creator/ClintEastwood himself contacted S&W representative Bob Sauer, who had several assembled from parts at the factory. Smith & Wesson reintroduced the Model 29 shortly after the film's release.
* ThrowItIn: Andy Robinson improvised several of Scorpio's lines, including the "hubba hubba" bit over the telephone and "my, that's a big one" when Harry pulls his gun in the park. The flip that Scorpio does when he is shot by Harry in the stadium was also Robinson's idea.
** The first choice for the role of Harry was Creator/PaulNewman, who declined on political principle. The filmmakers then offered the role to Music/FrankSinatra. Unfortunately, however, due to hand and wrist injuries he sustained while shooting ''Literature/TheManchurianCandidate'', Sinatra could not hold the gun correctly.
** Creator/JohnWayne lobbied hard for the role of Harry but the studio felt he was too old for the part.
** The screenplay for the first film went through numerous iterations and had several potential endings, including one in which Scorpio gets dispatched by a Marine sniper rather than Harry himself. Eastwood felt that the later drafts were overcomplicating the core premise and opted for one of the earliest screenplays written instead.
** Creator/AudieMurphy was initially offered the role of the Scorpio Killer, but declined due to fears of scarring young children.
* WorkingTitle: The title of the first film's script was ''Dead Right''.
