Directed by Hagishima Tatsuya, Kimi ni Shika Kikoenai (a.k.a. Calling You) is based on the same-titled light novel series by popular writer Otsuichi. Like Otsuichi's Waiting in the Dark, which was also recently adapted for the big screen, Kimi ni Shika Kikoenai revolves around two lonely young people who find each other in an uncommon manner. The film's strengths lie in its haunting, empathetic story and genuinely affecting performances from young leads Narumi Riko and Koide Keisuke. At only 15 years old, Narumi Riko has established herself as one of Japan's best young actresses, already with seven years of acting experience under her belt and a maturity that belies her age. The beautiful actress has found both popularity and acclaim with her many television outings, as well as subtle performances in films like Shindo and How to Become Myself. Koide is also a familiar face to audiences, having appeared in many popular youth films and dramas like Pacchigi!, Linda Linda Linda, and Nodame Cantabile, and he takes on his first leading film role in Kimi ni Shika Kikoenai.
