2013 South Korean Film The Suspect

Ji Dong-cheol was once one of the top special forces agent in North Korea, but after a change in political system, he was abandoned by his government while on a mission. He goes on the run, seeking his wife and daughter who were sold as slaves to China, only to discover their corpses. When he learns that an ex-colleague was behind their deaths, Dong-cheol goes on a vendetta for revenge, defecting to the South to chase his family's killer. Now living incognito, he searches for his nemesis during the day, and at night works as a personal chauffeur for Chairman Park, a business executive with ties to Pyongyang. One night the chairman is attacked and killed by an assassin, but not before handing over a special pair of glasses to Dong-cheol. The South Korean intelligence service, a member of which frames Dong-cheol for the murder, goes on the hunt for the beleaguered former spy. The manhunt is led by Min Se-hoon, a colonel and drill sergeant with whom Dong-cheol shares a past, and Kim Seok-ho, a corrupt director of the NIS. Aided by a feisty documentary filmmaker, Dong-cheol goes on the run again while trying to recover top-secret materials that his dying boss sent him to find.

Yoon Kye-sang was originally cast in the lead role, but dropped out after co-star Choi Min-sik left the project.

Gong Yoo was eventually cast, and the protagonist's name "Ji Dong-cheol" is similar to the actor's birth name, Gong Ji-cheol. To create the right physique for his role, Gong went on a diet for three months to reduce his body fat. He learned the Russian martial art Systema for the film's fight scenes, and performed car chases, rock climbing and skydiving at the Han River without using stuntmen.

The film was partly shot in Puerto Rico in April 2013.
