Peter Debruge Chief Film Critic In 99% of Hollywood movies, the goal is to make the stunt work invisible. Audiences are supposed to believe that the star — or better yet, the character he plays — put his own life at risk jumping off buildings, blowing up cars or duking it out with squads of bad guys. In “The Fall Guy,” the stuntman gets to be the hero (of an insanely overcomplicated story), while the star is a prima donna who claims to do all his own stunts but needs his double to step in when things get tough.
