With "No Breathing" set to premiere by the end of the month, a new official poster and a behind-the-scenes footage of the photo shoot is released for the viewers who are looking forward to the movie.

This new poster consists of the movie's main cast Seo In Guk, Lee Jong Suk, Girls' Generation member Kwon Yuri, Kim Jae Young and Shim Min Chul smiling together for the camera.

In the behind-the-scenes footage, not only do the cast show their chic and charismatic side, they also played and goofed around with each other, setting a comfortable atmosphere for the photo shoot.

"No Breathing" is a swimming sports movie with central themes of love and rivalry among the swimmers. Lee Jong Suk plays the role of Woo Sang, an ambitious dreamer who always aims to be number one.

This movie is also the big-screen debut for Seo In Guk, who plays the character Won Il, a swimming prodigy who avoided swimming due to certain circumstances, and Kwon Yuri, who plays the character Jung Eun, an aspiring musician and the childhood friend of the two swimmers.

"No Breathing" premieres on October 31.
