The latest “hot” movie is an action flick starring two of Japan’s most narcissistic rock stars. Gackt (photo), who is enjoying huge success these days as a solo artist and in various TV commercials, came up with the script for “Moon Child” and co-stars with Hyde. Both singers made their names with visual rock bands, Gackt with the short-lived Malice Mizer and Hyde as front man for L’Arc en Ciel. Despite his ability in several languages and being classically trained in a virtual orchestra of instruments, Gackt trades very much in his image as the cool silent type. But recent commercials have revealed a sense of humor that indicate previously hidden depth to his character.
