“We are legends, and legends never end,” declares one of the masked bruisers in this documentary about the Mexican wrestling federation CMLL (Consejo Mundial de Lucha Libre) and the long, colorful history of free-form wrestling at the Arena Mexico in Mexico City. One hardly expects wisdom from guys who like to kiss their own biceps, and the performers singled out by directors Alex Hammond and Ian Markiewicz provide little insight into what makes them tick (aside from Último Guerrero, who helpfully explains, “I love making people angry”). But their enthusiasm for the sport and its traditions is contagious, spanning the generations (Blue Demon, a big star from the 50s through the 80s, has been succeeded by his adopted son Blue Demon Jr.) and focusing the mind on important matters (the exact spot at the Arena Coliseo where wrestler Sangre India fell out of the ring onto his head and died). In English and subtitled Spanish.
