"Director Joseph Kosinski decided that he wanted the suits to actually light up, so
that the actors would illuminate each other on set. The filmmakers created costumes
using brand-new technology that allowed for sleek, streamlined suits that could
glow without the help of visual effects. They look great on-screen, but they were a
nightmare for the actors who wear them."
