U-Know Yunho and Choi Siwon transform into coast guards for 'Poseidon'

Super Junior's Choi Siwon and TVXQ's U-Know Yunho transformed into coast guards recently. Choi Siwon tweeted, "U-Know Yunho playing the part of Kang Eun Chul. One day in Japan, and one in America, no matter how busy and tired he is when the cut is finished, he's the kind of passionate senior that yells, 'Director, one more time!' I want to clap for the person that is Yunho. You worked hard!" He also added a photo of the two dashingly good-looking men with their thumbs up in their coast guard garbs. Fans commented, "I'm so looking forward to 'Poseidon'," "The uniform looks good on both of you," and "You two are really handsome." Source + Photo: Osen via Nate
