When Jameson and Kittridge resume their game of chess, Jameson has captured Kittridge's queen (leaving what would be a highly uncompetitive game). Once Jameson has made his first move of the evening, as Kittridge takes hold of Jameson's hand, the black queen suddenly appears on the board, on the square e5, and there are white pawns on the squares e4 and f5. After the next reverse shot (as Jameson says, "Come on, Sam"), the black queen and those two white pawns are no longer on the board.

The September fire written of by "Maj. Hugh Skelton" was actually set by order of John Bell Hood, commanding general of the Confederate Army of Tennessee, in order to destroy all military assets which could be of use to the Union Army prior to his force's evacuation of the city.

When Walter is reading the diary of the Civil War soldier at the beginning of the program, he reads an entry from "Tuesday, September 11, 1864." September 11, 1864 was a Sunday.
At the end, when the dust starts blowing away it should blow in the opposite direction due to the direction of the wind coming from the window.
