The fire breath was inspired by bombardier beetles, small ground beetles of the family Carabidae. Their unusual defense mechanism involves ejecting two different chemicals from their abdomens that react to produce a hot, harmful spray. As Dan DeLeeuw explained, this was the real basis for the dragons' breath: "Our art director, Mike Meaker, had seen an African beetle with a similar defense mechanism. It sprays a chemical behind it and emits sparks to ignite the stream. So our idea was that the dragon has two glands behind its throat that produce chemicals. The dragon spits the liquids with muscles that squeeze the glands. When the two streams pass 15 or 20 feet, they ignite naturally in front of the dragon." Before breathing fire, the dragons recoil and shake their heads, then thrust them forward violently. This behavior was again based on spitting cobras.

Christian Bale initially planned to be genuinely gaunt and skinny for the film, reasoning that food would not be so easy to find in a post-apocalyptic environment and that most people would lose a serious amount of weight. But when he arrived for shooting and saw how big Matthew McConaughey had gotten, he changed his mind and had to go to the gym. Given that the two have an intense fight scene in the film, Bale figured that if both men had similar builds they would match up more evenly and therefore look more realistic.

Ireland's first major foot-and-mouth disease outbreak in nearly 40 years meant the production company needed special permission for its 2001 shoots in County Dublin and County Wicklow. At the time, the Irish public was being told to visit rural areas only for essential reasons and to avoid unnecessary travel.

The London scenes were shot around the old Hotel on the grounds of the Pigeon House power station in Ringsend, Dublin. The power station was decommissioned in 1976. A replica of this set could be seen at Disney in Paris. When the studio tour attraction was updated as a Cars-themed ride, the set was removed from Disneyland Paris.

Jack Gleeson plays an uncredited role as one of the audience members watching Christian Bale's Star Wars performance. Years later, the two would share a scene in Batman Begins (2005).

The rifle Quinn (Christian Bale) uses is Ulrik's Mauser Tyrannosaurus Rex in.577 Nitro. Like the.600 Nitro double rifle in The Lost World: Jurassic Park (1997), it is an expensive and rare weapon custom-made by expert gunsmiths. The weapon is said to have such severe recoil and irresistible firepower that even hunters in Africa keep it only as a backup weapon against a charging animal. Despite this tremendous firepower, the rifle does no more than anger the dragon. A close look at the front sight reveals that they used more than one rifle in the film, since the front sight changes in some shots.

In a later scene, Quinn extracts a gelatinous, frog-like egg from the carcass; the model was made of clear polyurethane with a latex dragon embryo inside. "For the scene where Christian cuts the egg out, we used the rig like a defibrillator, so the dragon reacted with a kind of wobble," Martin said. He also recalled: "after we stood it up, the director took a walk around it. It was a tense moment, because he hadn't seen it since it was half-finished, but he said 'you did a number' and that was very encouraging. It was shot over several days in a smoky environment. Under wet conditions we dripped fake blood onto the dragon, so it was like a slaughterhouse inside -- and there were seats where our team controlled the pneumatics. They had to hand the egg to Christian because the egg was covered in slime and he couldn't grip it." The model was taken apart and distributed to different locations for another (deleted) scene, in which Quinn and the others see the half-eaten carcasses of multiple female dragons up close.

To make the dragon's scales move realistically, The Secret Lab solved the problem by redesigning a hair-generation program previously used for 102 Dalmatians to generate scales instead of fur. CG supervisor Adolph Lusinsky said: "It was Hank Driskill's idea to modify the fur system we developed for 102 Dalmatians to grow scales. The first test was growing scales on some dog animations we had. It looked like corn on the cob, but it told us we were on the right track. At first we were going to make the skin like a snake's; however, a snake's scales are shiny -- which made the dragon look like a plastic toy -- and the herringbone pattern blew out the dragon's scales. Then we rented alligator and crocodile hides and photographed the different scales. For example, the scales running along the arm, where the animal has to bend, tended to be more pebbly than the armored scales on the back. We actually took a lot of those references and put them directly onto our dragon." Ultimately the surface of the dragons' skin was covered with thousands of individual digital scales that could realistically overlap and interact. Displacement maps were also used for additional detail on certain areas of the body, including parts of the head. A special shader was used so the scales could hold their shape when the skin stretched.

The main part of the design work was actually done by traditional sculptors. Art director Miles Teves was almost the first artist on the creative team to produce both concept art and sculpture, and he was the most influential artist on the final dragon design. This unusual and intense design process lasted a total of 9 months, covering all of pre-production and two months of production.

Crocodiles, lizards and snakes were used as references for both the dragons' skeletal structure and their scales. Advanced digital muscle systems created an infrastructure that allowed animators to focus on real performance while achieving subtle, realistic muscle movement. The same applied to the digital skin, which stretched and contracted realistically when the model moved. The effects team wanted to avoid a leathery look on the creatures' skin, so they needed to find a technique to replace displacement maps. Digital effects supervisor John Murrah said: "Dan didn't want displacement maps for the scales. In case we had close-ups, he wanted to see the scales moving realistically, sliding over each other, with only the skin between the scales stretching, not the scales themselves."

Different digital models with subtle differences were created to depict sexual dimorphism in the creatures. The female dragons were designed to be 160 feet long with a 240-foot wingspan. The male bull, the first dragon to awaken in an ancient underground cave, is 50 meters long with a massive 320-meter wingspan.

In a 2015 interview with the AV Club, Alexander Siddig (Ajay) said: "The only thing I remember about it was the first day. The first A.D. came into the trailer where we were all getting our makeup and our grime done and said, 'Guys, I need your attention, please.' We said, 'Yes?' And he said, 'Mm, Mr. McConaughey is going to be on set in about 15 minutes, and I have to give you an instruction from the producers that you must not call him 'Matthew' or 'Mr. McConaughey.' Nothing about McConaughey or his real life. You must call him Van Zan.' Van Zan was his character's name. 'And even if you meet him out on the street, even if you meet him in town in Dublin where we're shooting this film, you must call him Van Zan.' And that's literally all I remember about that film, because as the A.D. was leaving the building first, I shouted rather feebly, 'And he should call me Elvis!' But he didn't call me Elvis. In fact, he didn't call me anything!"

Although the dragons were brought to the screen with computer-generated imagery for most of the film, a full-size model was built to depict the fallen dragon killed by Van Zan in the film's second act. The construction of the giant prop was commissioned from the London special effects house Artem; it was the largest project they had been given. Starting from Miles Teves's sculpture of the dead creature, a team of sculptors set to work bringing it to full size. The giant sculpture took 10 weeks to complete, and artists such as Miles Teves and Bruce Spaulding Fuller worked on it. Chris Martin, who was in charge of the construction process, said that to make sure the model copied the digital dragons exactly, "we scanned the maquette and generated cross-section data so we could create accurate polystyrene forms." "Then we took back the areas that would be rubber and put clay all over the forms to get a better final surface for molding. We made a multi-part fiberglass mold and used a two-part rubber backed with strong fabric because it was a very heavy piece. We used emulsion-type paints, some of them mixed with latex depending on where we applied them. The wing was translucent in places, so we used wood stain on almost all of it. The teeth were made of acrylic so you could see through them and we'd get a kind of x factor." Some of the teeth were removable: in a deleted scene, Van Zan was seen pulling one of the teeth from the dragon's mouth. The model, shaped over about 10 weeks, depicted the monster's entire body except for the left wing and tail, which were added digitally to the practical dragon in post-production. The full-size monster was designed to fold for easy transport, which made moving it from West London to the set in Southern Ireland easier. Because the dragon was not entirely dead after being reduced to ruins, puppeteers inside the body moved the mouth from within, making it twitch and adding subtle tongue and salivary gland movement. Pneumatic ribs built into the torso simulated the monster's final breath.

The Americans identify themselves as the "Kentucky Irregulars," something that means nothing to most American viewers but might mean more to Europeans because of differences in terminology. Irregulars are military personnel who are not part of the regular army, referring to militias, auxiliary forces and other elements. The "Kentucky Irregulars" are the Kentucky National Guard. (For non-Americans, the National Guard refers to military forces belonging to individual states rather than to the Federal Government.) Meanwhile, in colonial times (for example, when the British Empire ruled in America), Kentucky was a region known as very fertile hunting ground. Look, the Kentucky National Guard shows up to hunt dragons.

The resolution of the conflict in the film's story hinges on the existence of a single dragon individual that holds the key to the reproduction and thus the survival of the entire species. In early script drafts, this creature was conceived as a female (a 'dragon queen' nicknamed 'Ashley' by the production team), while the other dragons were male drones. At a certain point during script revisions, it was decided to show a dragon egg, but because the scene featuring it came before the climax and thus before the confrontation with the hierarchy, the sexes were swapped: the 'queen' became a 'king' and the other dragons became female. Following this change, several redesigns were attempted but ultimately abandoned; the final design of the bull male reflected the previous iteration. A clear sexual dimorphism is present: its head is proportionally different and it has longer horns, and the cobra-like 'hood' on its neck serves as an additional threat display before the creature attacks.
