In creating the world of The Eagle, the costume and production designers paid attention to every little detail, from masks to make up.
In addition to serving a strategic and tactical purpose, armor served a symbolic function, identifying rank and displaying the symbols and standards of one’s legion. Often the material itself denoted position and privilege. According to costume designer Michael O'Connor, “Marcus’ cuirass is metal and lutorius’ is leather suggesting a lower rank.” In designing the cuirass, the production team stayed closed to historical record, so, as O’Connor points out, “the Animal symbol on the cuirasses is a mark of the legion. The IX legion was a bull, the VI legion was a goat.”
