Professional stunt acting plays an important part in the special effects in some of Hollywood’s biggest movies.

It requires confidence, mental and physical strength of really courageous individuals. For the latest installment of Nowness’s “Endurance Test” series, director George Harvey highlights stunt actor Sian Milne, whose stunt work involves setting herself bonfire while wearing a protective suit within a controlled environment.

The short documentary gives a look at the level of discipline, mental strength and technical support required to pull off such dangerous stunts. In addition, the mindset the stunt actors take on. “What interested me about Sian and the team’s work is their ability to control their bodies under ferocious conditions,” filmmaker Harvey says. “Like meditation, it is surprisingly calm and controlled. These are actors who normally disappear into the background behind lead characters. Here, Sian steps into the light.”

Watch the stunning video below, which was coordinated by Game of Thrones stunt professional Rowley Irlam.
