* AFIS100Years100Laughs: #51
* {{Deleted Scene}}s:
** Censorship led to the trimming of two scenes.
*** Originally, the ImagineSpot of the Girl bathing went on to show the plumber dropping his wrench into the tub. As he reaches into the suds for it, the Girl doesn't seem to mind him invading her space.
*** This dialogue the Girl delivers to Richard after having her skirt blown by the subway also never made it to theaters:
---->'''The Girl:''' This one's even cooler! Must be an express. Don't you wish you had a skirt? I feel so sorry for you in those hot pants.
** A scene written, but probably never filmed, involved Richard's housekeeper finding a hairpin on his pillow, implying that he and the Girl slept together.
* ExecutiveMeddling: The act of adultery (consummated in the play) was removed by the censors, as were a few profanities and a few other bits considered risqué in 1955.
* FakeNationality: There's a whole tribe of fake Manhattan Indians at the beginning (as a narrator explains the anthropological origins of adultery).
* FollowTheLeader: At the time, very few movies opened with ArtisticTitle sequences. Saul Bass supplied the zany [[http://www.artofthetitle.com/title/the-seven-year-itch/ credits sequence]] here, and its success with audiences pretty much made his career. And in the 1960s and '70s, it seemed like ''every'' movie comedy opened with a cartoonish sequence of some sort, as did some SpaghettiWesterns.
* {{Homage}}: For some reason, a newspaper clipping from ''Film/TheDayTheEarthStoodStill1951'' is on the wall of our hero's office.
* ThePeteBest: Vanessa Brown played The Girl in the stage version alongside Ewell, but was apparently not asked to reprise the role for the movie. (Then again, Ewell was almost not asked to reprise ''his'' role; see WhatCouldHaveBeen below.)
* UnintentionalPeriodPiece: The film is a time capsule of the mid-1950s due to ValuesDissonance and other reasons. For starters, the entire plot is set in motion when the wives and children of New York City leave for New England to escape the summer heat, which would not be necessary just a few years later when air-conditioning became more prevalent and reliable. The female characters, almost without exception, are seen wearing the high-waisted, long-skirted "New Look" style of dress that was already starting to pass out of fashion when this movie was made. The script is littered with subtle and not-so-subtle references to the popular culture of the time period, some of them bordering on (and in one case even crossing) the CelebrityParadox: the characters going to a theater to see ''Film/CreatureFromTheBlackLagoon'', a pretty blatant parody of ''Film/FromHereToEternity'', etc. Perhaps most striking, however, is the characters' discussion of the [[Creator/MarilynMonroe Marilyn]] character wearing nothing but a bikini for a ''U.S. Camera'' photo shoot: we are told that police had to show up on the beach to keep the crowd under control, and until we actually see the photo, the way the characters refer to it leads us to believe that The Girl had actually been posing nude.
* WagTheDirector: ''The Seven Year Itch'' was meant to be shot in black and white, but Marilyn's contract stated that all her movies should be shot in colour.
* WhatCouldHaveBeen:
** There was a segment spoofing 1930s gangster movies that got left on the cutting room floor for some reason.
** Creator/WalterMatthau did a screen test for the role of Richard Sherman, but the studio [[HilariousInHindsight thought he was too risky an investment because he was still an "unknown"]]. Creator/GaryCooper, Creator/WilliamHolden and Creator/JamesStewart were also considered.
** Oh, and the movie that Creator/AlPacino chose over the aborted remake of this film? ''Film/{{Scarface|1983}}'' (which, actually, was itself a remake, but that's neither here nor there).
