Costume designer Janty Yates, who had to create costumes for Ridley Scott’s movie, shared that during the filmmaking process, the main actor needed 12 sets of armor. For each set of armor, they had to make 8 copies of it, 4 of them being made for the actor and 4 for the stunt man, including “clean” and dirty or muddy armors for different scenes. It was revealed that to make such costumes was challenging because they had to look real but at the same time be comfortable. That is why a lot of the costumes were made from foam rubber, making sure that in the end it would look as if it was made from metal.
