is a 2005 Japanese film directed by Katsuyuki Motohiro and written by Makoto Ueda, based on Ueda's 2001 play of the same name. The film stars Eita as a member of a university science-fiction club, and Juri Ueno and Yoko Maki as part of the neighboring photography club. Plot Summer Time Machine Blues is based around a group of friends in a science-fiction club who spend their days fooling around at the clubhouse. The boys play a game of baseball as their friend Yui Ito takes pictures of them nearby. After the game, the boys return to the clubhouse and head off to the bathhouse leaving the girls, Yui and Haruka to develop their pictures. While they bathe, Niimi gets angry because he thinks someone stole his Vidal Sassoon shampoo. On their way back, Komoto decides to sneak off to buy tickets at the theater for a sci-fi B movie.
