The Firestarter, Charlie, makes her way through the secret government facility blazing everyone in her path. Stunt doubles perform a very dangerous full body burn that completely engulfs them. The performer stands motionless for 18 seconds fully engulfed. Charlie continues down a hallway torching the heads of a swat guard. She makes her way into a concrete room where five military contractors confront her. An 80ft flame thrower fills the room, spraying everyone in front of her. Heat temperatures hit 800 degrees and was completed in five takes. A military grade flame thrower was used and purchased from the military. Because the fire suits worn by the stunt performers were not designed to take hits from a military grade flamethrower, specialized undergarments and additional gel and air assist also had to be used by each performer. No CGI was used.
