The opening battle scenes are taken from Raintree County (1957) and are printed as a mirror image of the original footage. The same scenes can also be seen in, amongst other films, How the West Was Won (1962).
In the wedding scene, the Corporal states that "the Yankees have broken through at Winchester." That occurred on Monday, Sep. 19, 1864 (the Third Battle of Winchester).
At the church, viewers observe Confederate soldiers with different colors of trim on their uniforms. The color red represents an artillery unit, blue represents an infantry unit and yellow represents a cavalry unit. Those traditional military branch colors are still used in the U.S. Army.
This film features three of Hollywood's busiest and most recognizable character actors, Paul Fix, Denver Pyle, and Strother Martin, but in roles for which they are not normally associated. Fix, often cast in roles related to the government, law, or law enforcement is here cast as a doctor. Pyle, often cast as a somewhat shady older relative is here a preacher. Martin, often seen either as a cowboy or Southern aristocrat type, is here a locomotive engineer.
