* ''Film/XMen'':

* ''Film/TheCrazies'' (1973). Colonel Peckham establishes a radio-phone link with higher authority, trying to get something done about the virus. The official on the other hand can be heard [[SkewedPriorities asking his aide for the colonel's first name]] in order to invoke this trope. Peckham angrily cuts him off in mid-greeting.

* Harry Potter calls Voldemort "Tom" during their final battle. Unlike most other cases this is meant as an insult. Voldemort wants to be feared and being called by such a normal name reminds him of when he was nothing.

* ''Film/TheEnforcer''. DirtyHarry is partnered with a rookie female officer who's naturally defensive about any attempt to patronize her -- so much so that "Don't concern yourself, Inspector" becomes her CatchPhrase. Her FamousLastWords as she dies in his arms are "Don't concern yourself...Harry."

* Rachael from ''Film/BladeRunner'' loses her surname of Rosen from the book on which Blade Runner is based, ''Literature/DoAndroidsDreamOfElectricSheep''.

* Rachael from ''Film/BladeRunner'' loses her surname of Rosen which she had in the book which Blade Runner is based on, ''Literature/DoAndroidsDreamOfElectricSheep''.

* Lampshaded in ''Film/TheAvengers2012'' when [[PhilCoulson Coulson]] shows up at Stark Tower.
-->'''Pepper Potts''': Phil!\\
'''Tony Stark''': Phil? Uh, his first name is "Agent".
** Note that it is completely in character for Pepper to learn his name, and for Tony to not. [[spoiler: This gets a CallBack after Coulson is killed by Loki.]]
-->'''Tony''': [[spoiler: And there's one other person you pissed off. His name was Phil.]]
* It is a point brought up by Pep Strebeck to Joe Friday in ''{{Franchise/Dragnet}}'' that friends call each other by first names.

* EVERYONE in ''Film/TheRoom''- nobody seems to have a last name (Except possibly Chris-R, but who knows what that stands for)

* In ''Film/PiratesOfTheCaribbeanTheCurseOfTheBlackPeal'', Elizabeth is furious that Jack refers to her by her first name during their first encounter - "It's ''Miss Swann!''". Will refuses to call Elizabeth by her first name, despite their knowing each other as children, because of their difference in social status; when Elizabeth accepts it and calls him "Mr. Turner", he is deeply grieved. Later, Jack calls Elizabeth "Captain Swann" to acknowledge (with some difficulty) that she has one of the pieces of eight; Bootstrap Bill calls his own son "Captain" and Will calls his own father "Mr. Turner" to acknowledge their roles on the ship; and Barbossa calls Elizabeth "Mrs. Turner" to acknowledge her marriage (though this one is a callback to the first movie, where Elizabeth passed herself off as Elizabeth Turner). Such careful usage was not common in the movies.

* ''Radio/OurMissBrooks'': Significantly, making up after an argument midway through the [[TheMovie cinematic]] [[GrandFinale grand finale]], Miss Brooks and Mr. Boynton finally move to a first name bais, "Connie" and "Phillip" respectively.
* In ''{{Pirates of the Caribbean}}'', Elizabeth is furious that Jack refers to her by her first name during their first encounter - "It's ''Miss Swann!''". Will refuses to call Elizabeth by her first name, despite their knowing each other as children, because of their difference in social status; when Elizabeth accepts it and calls him "Mr. Turner", he is deeply grieved. Later, Jack calls Elizabeth "Captain Swann" to acknowledge (with some difficulty) that she has one of the pieces of eight; Bootstrap Bill calls his own son "Captain" and Will calls his own father "Mr. Turner" to acknowledge their roles on the ship; and Barbossa calls Elizabeth "Mrs. Turner" to acknowledge her marriage (though this one is a callback to the first movie, where Elizabeth passed herself off as Elizabeth Turner). Such careful usage was not common in the movies.

** In ''StarTrekIntoDarkness'', when Scotty resigns in protest [[spoiler: over the missiles]], he makes a last appeal for Kirk to reconsider and calls him "Jim".

* ''Film/XMen'': Charles Xavier (Professor X) and Erik Lehnsherr ({{Magneto}}) always use their first names when speaking to or about each other. Only a handful of others are on a first-name basis with them.
** ''Film/XMenDaysOfFuturePast'':
*** While the public and most other characters refer to Erik (Magneto) and Raven (Mystique) by their mutant code names, Charles and Hank still remain on a first name basis with both of them, and vice versa. This is also presumably true for Alex, who still addresses his former allies as Raven and Erik.

**** Or rather an off-stage HeelFaceTurn, given this dialoge from XMenUnited:
-->'''Magneto:''' What is your name? \\
'''Pyro:''' John? \\
'''Magneto:''' No, what is your ''real'' name?

'''Pyro:'''John? \\

'''MAgneto: No, what is your ''real'' name?

* Lampshaded in ''Film/TheAvengers'' when [[PhilCoulson Coulson]] shows up at Stark Tower.

* The only character in ''Film/BackToTheFuture'' to address Doc as "Emmett" is Clara Clayton, his love interest.

* In ''TheGunsOfNavarone'' Colonel Andrea Stavros insists on going by his unadorned first name, in spite of outranking everyone else in the team. This is a confirmation of two things; that the Greek army is disbanded, and that he defers to Captain Mallory and Major Franklin since this is an Allied operation.

* After the heroes save Utah in ''Broken Arrow'' and seem headed for the [[SmoochofVictory]], [[FirstNameBasis]] happens instead. They shake hands, and the last lines of the movie are "Riley Hale." - "Terry Carmichael."

* After the heroes save Utah in ''Broken Arrow'' and seem headed for the [[Smooch of Victory]], [[First Name Basis]] happens instead. They shake hands, and the last lines of the movie are "Riley Hale." - "Terry Carmichael."

* In the ''Films/XMen'' films, just like in the comics, Charles Xavier (Professor X) and Erik Lehnsherr ({{Magneto}}) always use their first names when speaking to or about each other. Only a handful of others are on a first-name basis with them.
** In ''Film/XMenDaysOfFuturePast'', while the public and most other characters refer to Erik (Magneto) and Raven (Mystique) by their mutant code names, Charles and Hank still remain on a first name basis with both of them, and vice versa. This is also presumably true for Alex, who still addresses his former allies as Raven and Erik.
** Surprisingly, the elderly Magneto calls Bobby by his first name instead of his codename (Iceman). This indicates that Erik must have gotten to know Bobby on a more personal level during their war against the Future Sentinels.

* ''Film/TheCrazies'' (1973). Colonel Peckham establishes a radio-phone link with higher authority, trying to get something done about the virus. The official on the other hand can be heard [[SkewedPriorities asking his aide for the colonel's first name in order to invoke this trope]]. The Colonel angrily cuts him off in mid-greeting.
