Over 15 million tickets sold and still counting.
The movie "Roaring Currents" has roared past its competition to claim sole possession as the highest-grossing film in Korean history.
Choi Min-sik, who plays admiral Yi Sun-shin in the period film, says he still can't fully digest all the attention.
"This is all surreal to me. I'm glad that the movie was able to open up ground that allows different generations to come together."
"Korea's most watched movie hasn't been just a hit on the silver screens. The craze has permeated into other industries, leading to increased sales of books and even modules, related to Admiral Yi."
Miniatures of the battleship used during the battle have tripled in sales at this specialty shop and interest is growing.
"Watching the film has broadened my view, and these replica figures and even unknown books on Admiral Yi now catch my attention."
Sales of biographies and non-fiction titles are also booming.
More people are looking to read up on Korea's most famous admiral, and according to Kyobo Book Store, the number of books sold has surged six-fold compared to the same period last year.
As for why all this interest movie critic Jeon Chan-il says the timing of its release has played a big role.
"The fact that there isn't a firm role model like Admiral Yi in the nation is eventually coming to light through the popularity of this movie. It means that many people are wanting to rest and lean on such leadership that's shown by the character."
