Decibel is an action thriller that follows a terrorist, who wants to take over the city with a special bomb that explodes when there is a loud noise, and a former Navy commander, who becomes the target of the terror. On Wednesday, Kim Rae Won shared what it was like working with Lee Jong Suk and Cha Eun Woo. About Cha Eun Woo, the actor shared, ŌĆ£Eun Woo is excellent on the set. He was the youngest, so he always had a smile on his face, and everyone wanted to help him.ŌĆØ When asked about any advice he mightŌĆÖve given Cha Eun Woo, he answered, ŌĆ£I did have a little talk with him, but I think Jong Suk talked more with him since he had more scenes with Eun Woo.ŌĆØ Kim Rae Won then moved on to talking about Lee Jong Suk. ŌĆ£Jong Suk opened up to me first and asked lots of questions,ŌĆØ he shared. ŌĆ£Actually, IŌĆÖm very careful about discussing acting with actors on the set just because IŌĆÖm a senior. So IŌĆÖd say one thing very carefully, and he was so flexible and amazing that he reflected on it and turned it into his own. That really isnŌĆÖt easy.ŌĆØ Lastly, he added, ŌĆ£Of course, the fact that Jong Suk trusted me wouldŌĆÖve played a part in it.ŌĆØ Source (1)
