Heartthrobs Lee Jong Suk and Seo In Guk have been cast in the upcoming film 'No Breathing'.

The film's production agency announced the news as they stated, "Lee Jong Suk and Seo In Guk's casting have been confirmed."

Lee Jong Suk will play the role of Woo Sang who is an ambitious, young swimmer chasing with a big future ahead of him and always strives to be #1. Meanwhile, Seo In Guk will make his film debut through his role as Won Il who is a swimming prodigy but avoids swimming, until one day when he decides to return to the sport.

Lee Jong Suk shared, "It is a big honor to be cast in the nation's first swimming film. I am currently receiving intense training to act out the talented national athlete so I ask that you look forward to it."

Seo In Guk shared, "More than anything else, I wanted to be 'Won Il' and I want to quickly get in tune with that character. I think this will also be a big help to my development as Seo In Guk the human being."

Filming for the movie will begin in May and the film is set to premiere later this year. Guess we'll be seeing the two in swimsuits soon enough!
