* WhatCouldHaveBeen:
** Creator/AdrienBrody and Creator/JoaquinPhoenix were considered to play Lincoln and Henry respectively. Brody was one of the final choices before losing out to Benjamin Walker while Phoenix turned down the role to do ''Film/TheMaster''. With Phoenix's penchant for MethodActing, the film could have been somewhat CrazyIsCool.
** Creator/TomHardy was approached for the title role of Lincoln, but had to turn it down due to scheduling conflicts with ''Film/TheDarkKnightRises''. Other candidates included Creator/EricBana and Creator/TimothyOlyphant.
** [[Music/NineInchNails Trent Reznor]] was approached about scoring and playing a minor part in the film, but the news leaked before the final decision and Reznor voted to pass on the project as the surprise element of his participation had already been lost.
