SIGNING on to zombie movie “Rampant” was a no-brainer for lead actors Hyun Bin and Jang Dong-gun as it finally gave the pair of real-life best friends the chance to work together.

At a press conference to promote the film in Singapore on Tuesday afternoon, Jang, 46, says in Korean via a translator: “One of the main reasons why I took on this movie was because I would get to act with Hyun Bin. There is a high level of trust on the set because we’re so familiar with each other.”

Never mind that the two had to play rivals in the movie — Hyun is a prince in the film, while Jang plays an ambitious war minister who schemes to take advantage of a growing zombie problem in the kingdom to overthrow the royal family.

The two superstars, who have been friends for more than a decade, are also teammates on a South Korean celebrity baseball team known as the Playboys.
