Director Timur Bekmambetov had Benjamin Walker view John Ford's YOUNG MR LINCOLN as preparation for his role in VAMPIRE HUNTER.
The battle scenes featured a lot of Civil War reenactors as extras, most of whom wore their own costumes.
Joaquin Phoenix was the first choice for the role of Henry Sturgess, but turned it down. Dominic Cooper was cast instead.
Robin McLeavy was considered to play Lincoln's wife Mary Todd, and was later cast as Lincoln's mother Nancy.
Tom Hardy was approached for the title role of Lincoln, but had to turn it down due to scheduling conflicts with The Dark Knight Rises. Later, Eric Bana, Timothy Olyphant, Adrien Brody, Josh Lucas, James D'Arcy and Oliver Jackson-Cohen were considered to play the role before Benjamin Walker was cast.
