The big success of the South Korean movie "The Train to Busan" earns praises and a confirmation for a sequel. Since Goo Yoo will no longer cast in the second film, fans are in a frenzy of thinking that 'Descendants of the Sun' actor Song Joong Ki might perfectly suit the role.

"The Train to Busan 2" lines up with the most sought after ideas to look forward to in cinemas after seeing how fans and moviegoers alike embrace the South Korean zombie film. It was reported that the movie has 10 million viewers and is still counting, according to GamenGuide.

"I talked about this with Director Yeon Sang Ho, and I said that I thought my character Seok Woo might be living somewhere as a zombie." He added, "But Director Yeon said that when Seok Woo fell off the train, he broke his neck and died."

It was a painful ending for Woo who became a zombie. He sacrificed his life to get his daughter out of danger, International Business Times reported.

However, with Yoo no longer reprising his role as Seok Woo, who fell off the train tracks just to save his daughter, a big question hangs in the air. Who will now replace him as the lead actor? Rumors surface that it will be Song Joong-Ki who stars in 'Descendants of the Sun' will be crowned as the new Seok Woo.

As of the moment, Ki is presently filming his historical movie, "Battleship Island" where he stars as Park Moo-Young as a Korean Independence group member. The Daily Sports recently voted him as the most influential person in terms of the entertainment industry.

Meanwhile, it was reported that the "Train to Busan" is making waves and has superseded "Cold War 2" as the most successful Chinese-language film bagging $8.52 million.

"Train to Busan" was produced by Seoul-based Next Entertainment World (NEW) along with Hollywood studios. Sony Pictures and the 20th Century Fox also serve as the producers while Canal Plus, EuropaCorp, and France's Gaumont negotiate for the remake rights with Contents Panda.

For the meantime, fans should just be happy with sequel confirmation. No release date has been disclosed for "Train to Busan 2" but rumors say that production will start on 2017.
