Plot introduction: Patrick Suavage (Jean-Claude Van Damme) has just returned from three years of war in Afghanistan and Iraq, and now he is hired as a bodyguard in a private area. The client is a former world heavyweight champion who now runs a black market boxing match. In order to ensure the safety of the client, Jean-Claude Van Damme organized an experienced fighting team named "The Hard Corps". Behind the scenes of the film: The director of the film is Sheldon Lettich, who was once the screenwriter of "Blood Game". The film made Lao Shang famous, and later he also directed Lao Shang's "Double Shadow Weilong" and "Iron Fist Invincible". "Hard Corps" is the fourth collaboration between Sheldon Lettich and Jean-Claude Van Damme as directors. Sheldon Lettich is familiar with shaping muscular men. The role he designed for Jean-Claude Van Damme is an American soldier who has been retired for three years and works as a bodyguard for a boxing champion to make a living. He formed a bodyguard team called the Hard Corps to protect the safety of the champion. This world champion also has a sister, who fell in love with Jean-Claude Van Damme. Shooting highlights: The film of The Lone Hero Returns to the Gangs began filming in November last year, and the main scenes were completed in Romania and Canada. The "flip-flop" of Wesley Snipes, the Blade Warrior, added some waves to the film. The earliest news was that he would play a boxing champion, but there was no trace of Blade on the set. It seems that Blade, who has special skills, disdains to be protected. Without Blade, the focus is naturally on Jean-Claude Van Damme, who is an old man with old arms and legs, and he personally designed all the fighting scenes. In addition, this film is also the first time that Jean-Claude Van Damme has partnered with a dog. The villain in the film is definitely unlucky. Not only will he be kicked away, but he may also lose his life in the mouth of a vicious dog.
