Ironclad is loosely based on the life of William d'Aubigny, who commanded the garrison at Rochester. Historians disagree on the exact number of forces defending Rochester Castle; estimates range from ninety-five to one hundred and forty knights, supported by crossbowmen, sergeants and auxiliaries. When King John took the castle, most of the nobles were imprisoned or exiled. The French forces did not reach England until six months after the siege ended.

According to writer and director Jonathan English, the bloody hackings of arms and legs were done with old-fashioned prosthetics rather than CGI.
- #003
According to writer and director Jonathan English, Daniel O'Meara really did eat a bug during the siege, though he is not sure the actor swallowed it.
- #004
Although the subtitles spell Brian Cox's character's name as "Albany", historians render it variously as William de Albini and William d'Aubigny. The latter is correct.
- #005
Paul Giamatti shot his role in seven days.
- #006
The Danes, shown as pagans in this film, had in fact already been Christianized by that period. The bulk of King John's mercenaries were not Danish but consisted mostly of Flemings, Provençals and Aquitanians.
- #007
When King John cuts off Baron Albany's hands and feet, there is a moment as he walks alone toward a gloomy marsh. Beside him is a shrub with bright yellow flowers. The shrub is the emblem of the kings before and after him, the Plantagenets, as history knows them.
- #008
The "Danish" forces speak Hungarian.
- #009
Thomas Marshal (James Purefoy) was broadly based on the medieval knight and statesman William Marshal.
- #010
William d'Aubigny commanded the garrison, but historical records show that he was not tortured or killed during the siege, nor was he a noble wool merchant.
- #011
The closing narration claims this battle was ultimately one of the first French victories that led to full triumph. However, after King John's death in 1216, many English rebels preferred the weak English King Henry III to a strong and experienced French ruler. This meant that many English rebels took refuge in the Royalist camp and the rebellion was defeated by Royalist forces in 1217.

Ironclad depicts King John's siege of Rochester Castle in 1215. A replica of the castle was built in 14 weeks.
- #013
The handheld combat footage was shot by a costumed camera operator.
- #014
Director Jonathan English hired cinematographer David Eggby because Eggby had shot the original Mad Max (1979) and English wanted the same level of instinctive energy.
- #015
Shot entirely in Wales, Ironclad is the largest independent production ever filmed there.
- #016
Angus Macfadyen was originally cast as Jedediah Coteral, but he left when the project was refinanced. Jamie Foreman was brought in to replace him.
- #017
Ironclad is decidedly not based on William Marshal. Marshal did not take the cross until he was on his deathbed, so he was never a fighting Templar. He also fought for King John against the French and won a great victory at Lincoln (the Battle of Lincoln Fair). Although Marshal stood by John, he was known as a royalist who stood by Henry II, Richard I, John and Henry III. His loyalty was to the crown rather than to the person, and after John's death he became the reluctant regent for the young king Henry III. Marshal reissued Magna Carta, as his seal shows. John, meanwhile, never signed Magna Carta because he could not write, and in any case contemporary documents were sealed, never signed.
- #018
The film's financing became genuinely complicated, with the budget cut at one point. This meant the originally proposed cast had to be dropped and recast (except for James Purefoy and Paul Giamatti), and it explains why the film has 18 executive producers.
- #019
James Purefoy does not speak his first line of dialogue until the 13th minute of the film.
- #020
Megan Fox was said to be attached to the film.
