V is for Vendetta
For the scene when V emerges from Larkhill, stunt double Chad Stahelski literally walked through fire, wearing just a special fire resistant gel and a g-string. Stahelski's body temperature had to be lowered before the scene was shot, and luckily, it was 3 below zero the night of the shoot. 15 minutes before a take, he would put on ice cold flame resistant clothing, and once he took them off, he would be covered with fire resistant gel which had been icing all day long.
