According to "Train to Busan 2" rumors, the film does not have an official production and release date yet, but there are speculations that "Descendants of the Sun" actor, Song Joong Ki, is the likely replacement for Gong Yoo in the upcoming film.
According to Indie Wire, the internet is abuzz with "Train to Busan 2" rumors that Yoo will be replaced by Song Joong Ki or Lee Min Ho of "Legend of the Blue Sea" fame. Sources claim that between two actors, Song Hye Kyo's alleged beau is the likely choice to replace Yoo's character in the apocalypse-themed movie.
Most fans are already aware that Yoo's character gets infected with a virus in "Train to Busan," making it impossible for him to be the lead actor in follow-up film. However, unless "Train to Busan 2" finds a mysterious cure for the disease, it is unlikely that Yoo will return for the sequel.
If "Train to Busan 2" rumors are indeed true, Joong Ki will feature as the doctor who is working on the antidote that will cure this deadly disease. His character is also speculated to save Kim Su-an's daughter after he dies trying to protect her. Reports also claim that his character will raise Su-an's daughter in "Train to Busan" sequel, Movie Pilot reported.
Meanwhile, as the filming is reportedly scheduled to begin in June 2017, Min-ho may not be a part of the production agenda as the actor is supposed to leave for his military service within this year. For now, there is no update about when the actor has to enlist his services.
As "Train to Busan 2" rumors are rife online, no update about the upcoming film's release or cast details has been officially announced. For now, the film's reported plot details and Gong Yoo's replacement by actors Joong Ki or Min-ho are mere rumors, so the fans should take this update with a grain of salt.
