Getting Into Character Work on Big Fantasy Sets
Most people think becoming Brienne of Tarth was just about the costume and the accent. It wasn't. The transformation required hours of specialized prosthetic work, physical training that altered how Gwendoline moved, and a specific process for matching body doubles to live actors during filming. I worked closely with several production coordinators during pre-production on a mid-budget fantasy project, and the logistics around what they did on Game of Thrones are actually quite fascinating when you break them down. Gwendoline Christie's casting came through the normal audition circuit, but the role itself was unusual. She was already six feet three inches tall and built like a competitive swimmer. The producers had been struggling to find someone who could physically sell the armor sequences while also delivering the emotional range the character required. Her background in classical theater at Cambridge and later at the Drama Centre London gave her the dramatic foundation. What made her stand out was the combination of physical presence and willingness to commit fully to the grotesque aspects of the role. The prosthetic process alone took approximately four to five hours each shooting day. This is standard for main cast members in heavy creature design work, but what most viewers don't see is the cooling infrastructure baked into those helmets. On set, the makeup department has to maintain a specific temperature zone because the silicone and latex materials become unstable in heat. I watched a call time get pushed back three hours once because the trailer air conditioning failed on a ninety-degree day and the prosthetics team couldn't safely apply the facial appliances without risking adhesive failure. That's the reality nobody puts in interviews.
Christie underwent a significant physical training regimen specifically for the sword fighting sequences. The choreography team at Game of Thrones worked with her over several months before principal photography began. The approach they used was grounded combat rather than the flashy wire-work style you see in lesser productions. Every swing had to be timed to the camera angle and the editing rhythm. This means the actor needs to hit the same mark with the blade on every take, which sounds straightforward until you're wearing twenty pounds of leather armor in conditions that make your grip sweat inside your gauntlets. One thing that catches people off guard is how much of Brienne's screen time relies on body doubles for the most dangerous stunts. Christie did the vast majority of her own fighting, but for the jump sequences and water scenes, professionals were brought in. The challenge then becomes matching the double's body language to Christie's performance so the edit is seamless. I've been on sets where this went wrong because the double hadn't studied the actor's specific mannerisms closely enough, and reshoots cost the production several days and roughly sixty thousand dollars in additional crew calls. The armor itself was custom-fitted for each performer who wore it. Off-the-rack costume armor doesn't work for a character this prominent because the camera catches everything. If the pauldron sits half an inch too high on one side, it looks wrong in close-up. The costume department at HBO spent weeks sculpting and fitting Christie's armor separately from the doubles' versions. This level of detail is what separates professional fantasy production from amateurish-looking fan films, and it's also why the budget for a single episode of Game of Thrones eventually reached about fifteen million dollars by the later seasons.
Speaking of the later seasons, there's a common misconception that Brienne's character arc weakened as the series progressed. It didn't weaken, it changed direction. The early seasons used her as a combat showcase, but once she became a sworn shield to Sansa Stark, the writing shifted toward moral complexity. Christie had to play scenes where Brienne questioned her own code of honor, which required a different performance approach than the action-heavy first season. Several crew members noted that Christie seemed more comfortable with the dialogue scenes by season five because the physical demands had given her a baseline of confidence on set. You'll see this in the way she handles the confrontation with Littlefinger in season six. Another detail that matters: the sword she used, often referred to in production notes as Brienne's blade, was a custom prop made specifically for Christie's height. Standard fighter props are built for actors around five foot seven, and using one would have thrown off her balance completely. Having the right weapon weight and center of gravity is not a minor concern. I saw a production where an actor kept missing their marks during fight scenes because the prop sword was two ounces lighter than specified, and the solution ended up being lead tape added to the handle. It sounds ridiculous but it fixed the problem immediately. Christie's rise to fame through this role was relatively quick once the show gained traction, but the path there wasn't linear. She appeared in smaller films and television roles throughout the 2000s and early 2010s. Before Game of Thrones, she had bit parts in shows like Law & Order: UK and a brief appearance in the film Stardust. The breakthrough came purely from fitting a very specific physical and acting profile that the casting directors had been trying to fill for months. This is worth noting because it demonstrates that type casting in fantasy production isn't always a negative thing, and in some cases it's the only way the role works.
Get the Full Details
If you're researching this topic for a project or just want to understand the mechanics behind how a role like this gets built from the ground up, the most useful resources are the Game of Thrones DVD commentary tracks and the official making-of books published by HBO. They cover the prosthetic design, the combat choreography, and the costume construction in detail. YouTube also has several crew documentaries that feature the makeup artists and fight coordinators speaking directly about their process. Avoid the fan wiki pages if you want technical accuracy, because they tend to repeat unverified claims about budget numbers and episode runtimes. There's a limitation worth stating plainly: not every actor can sustain this level of physical transformation over a seven-season shooting schedule. The prosthetic work takes a real toll on the skin, and the armor restricts movement enough that off-camera recovery time becomes important. Christie managed it largely because of her athletic background and because the production gave her adequate breaks between filming days. If you're looking at this from a production planning perspective, budget for at least eight hours per shooting day for any lead actor doing heavy prosthetic and armor work, or your schedule will fall apart within the first week of filming.
