* AllStarCast: Though more of the HeyItsThatGuy character actor variety than the A-list star variety, although Daniel Day-Lewis, Sally Field, Tommy Lee Jones and Joseph Gordon-Levitt definitely all qualify.
* DoingItForTheArt:
** Spielberg has been researching for this film for '''12 years''', down to the correct wallpaper and books in the White House of 1865 and the right ticking noise for Lincoln's watch (Recorded from the actual one!)
** Creator/DanielDayLewis [[MethodActing accepted the role on the condition that he got a year to prepare.]]
* FakeAmerican: British-Irish Creator/DanielDayLewis, Scottish Peter [=McRobbie=], and Brits Jared Harris and David Oyelowo all play Americans.
* FakeBrit: Lee Pace as Fernando Wood (the real Wood was completely American.)
** He sounds that way because he is using elocution, the art of formal speech. Wood may have learned this "classical" sound in school, or picked it up by listening to actors (perhaps the extremely popular Booths) and others trained in public speaking. Bill Raymond as Schuyler Colfax, saying "The House recognizes Fernando Wood," is also using it. Some film actors still practiced elocution in the 1960s.
* OldShame: Has been an ''audience'' reaction during the voting scene; if they're from a state that had congressmen who did not vote yea, a groan can be heard in the theater (unless you're from Connecticut, in which case you'll be mad that the movie shows two House members voting against the amendment when in RealLife all four were in favor of it).
* PlayingAgainstType: Sally Field, who normally nowadays plays sweet, [grand-]motherly types, as controlling, bitter, mentally unstable Mary Todd Lincoln.
** While he's certainly played heroic characters before, Daniel Day-Lewis' turn here is generally subtler than some of his more recent work in ''Film/ThereWillBeBlood'' and ''Film/GangsOfNewYork''.
* RealitySubtext: Daniel Day-Lewis and Sally Field had only met in passing prior to this film. Mary's and Lincoln's relationship is fraught, to say the least; however, over the course of filming the two actors quickly came to adore each other.
** The great-grandfather of Michael Stanton Kennedy was a newspaperman from the town where his character, Hiram Price, lived. When filming the scene where the 13th Amendment passes, Kennedy started to cry and couldn't explain why until later, when he told Steven Spielberg "We're in this room recreating one of the most important moments in American history... and up there [in the balcony] with the press sat my great-grandfather."
* HeyItsThatGuy: Fans of ''Series/TheWire'' will recognize Davide Costabile (Thomas Klebanow), Boris [=McGiver=] (Lieutenant Marimow), and Bill Raymond (The Greek) as James Ashley, Alexander Coffroth and Schuyler Colfax, respectively.
* SavedFromDevelopmentHell: The movie had been in various stages of production for over 10 years before finally coming to screen.
* WhatCouldHaveBeen: Creator/LiamNeeson was attached to play Lincoln through most of the film's development, but dropped out in January 2010, believing he had become too old to play the part.
