I've seen the movie starring Tom Cruise "OBLIVION" that has been recently released in Japan. It was interesting as well as Science Fiction, but it was a great love story too. The stage of the story is the future of 2077, but Morse code comes out. The Morse code is used in the scene which Jack Harper 49 (Tom Cruise) shows his presence from the Empire State Building. Please check at the theater for more information!
