Big Bang's Daesung and f(x)'s Sulli will lend their voices for an exciting new 3-D animation movie called "Sammy's Adventures: The Secret Passage". "Sammy's Adventures: The Secret Passage" is a dynamic movie revolving around a sea turtle named 'Sammy' who was born on a California beach and travels around the world for 50 years alongside his friends, 'Ray' and 'Shelly'. The loveable and adventurous turtle will be voiced over by Daesung, and Sammy's adorable girlfriend 'Shelly' will be dubbed by Sulli. Sammy's best friend (and poser turtle) 'Ray' will be voiced by comedian Wang Biho. Reportedly, Daesung synchronized so well with his character that his fellow staff could not believe that this was his first time dubbing. The movie is scheduled for release on December 16th.
