South Korean zombie thriller "Train to Busan" continues to gain international attention and top box office charts globally. With this comes massive public demand for a sequel, and there are already several rumors about what would possibly go down in the next chapter of the film, with a working title of "Train to Busan 2."

In the adrenaline-pumping "Train to Busan," Gong Yoo's Seok Woo hops on a train to Busan with his daughter Soo An, played by Kim Su An. What they thought would be a quiet trip ends in a race for survival as a zombie outbreak hits South Korea.

In a recent interview, Gong shared his ideas for a potential "Train to Busan" sequel. He revealed that he pitched a plot to director Yeon Sang Ho, which would follow his life as a zombie.

"I told director Yeon Sang Ho that my character Suk Woo is probably living somewhere as a zombie, but then the director told me that Suk Woo already died by breaking his neck when he jumped off the train," Allkpop quoted Gong as saying.

Since it appears it would unlikely to have his character return for, Gong instead suggested that the story would be told in the perspective of Ma Dong Seok's character, Sang Hwa.

"I recommended that the sequel is made from Ma Dong Seok's point of view since Ma Dong Seok's character is alive as a zombie," the South Korean star added.

It's a plausible plot, considering that Sang Hwa's transition into a zombie was not shown in "Train to Busan."

There's been no official confirmation as to a sequel to "Train to Busan"; however, The Hollywood Reporter noted that major studios such as 20^th Century Fox and Sony Pictures are in a bidding war for the remake rights to the South Korean film.

France's movie studios Gaumont, EuropaCorp and Canal Plus are also circling the movie. It is said that French studios are interested in remaking the film since French people take the bullet train on the daily, making the story more relatable to the local audience.

"Train to Busan" first debuted at the Cannes Film Festival where it was screen under the Out of Competition category. It was commercially released in July and earned $28.8 million in its first five days. To date, the movie has earned more than $1.4 million in North America alone.
