Tony Kushner, the acclaimed playwright who wrote the screenplay, told me he was outraged that Courtney was getting his 15 minutes by complaining about a 15-second bit of film on a project that Kushner worked on for seven years.

The writer completely rejects the idea that he has defamed Connecticut, or the real lawmakers who voted “Aye.” He said that in historical movies, as opposed to history books where you go for “a blow-by-blow account,” it is completely acceptable to “manipulate a small detail in the service of a greater historical truth. History doesn’t always organize itself according to the rules of drama. It’s ridiculous. It’s like saying that Lincoln didn’t have green socks, he had blue socks.”

He feels that if he had changed the margin of the vote, or made someone a villain who was not in real life, that would have been inappropriate. (He’s one-up on Shakespeare there.) But he wants “wiggle room” on some things.

Spielberg’s production people called the National Archives in 2011 to get a copy of the original voting roll and to plumb deeply into the details of the vote on one of America’s most searing moral battles, even asking whether the vote was recorded in a bound volume or on loose ledger forms. That roll shows that the first two votes cast were “Nays” by Democratic congressmen from Illinois, Lincoln’s own state. Wasn’t that enough to show the tension?

Kushner explained that in his original script he thought, as in the musical “1776” or the Continental Congress or conventions, the lawmakers voted by state, so Connecticut would have been one of the first Union states to vote.

Harold Holzer, a Lincoln historian attached to the film, pointed out the mistake to Spielberg and Kushner, telling them that voting in those days was done alphabetically by lawmaker. But Kushner said the director left the scene unchanged because it gave the audience “place holders,” and it was “a rhythmic device” that was easier to follow than “a sea of names.” They gave fake names to the Connecticut legislators, who were, he said, “not significant players.”
