I read it a while back, forgot the title. The story follows an inexperienced actor who had such a convincing scene that the director of a movie gave him a torture scene. The reason for his amazing performance? He gets transported to the acting scene. This means he gets tortured, people die in front of him and the latest role he received was a guy who got murdered by a series killer. There wasn't much depicted in the manga, but it seems going somewhere and I am interested in finding out what it is called.
