Gintama is the story of an Edo era Samurai in a Japan where Aliens have invaded and taken over the Earth. Skyscrapers and traffic jams came to Kyoto centuries ahead of schedule, and the simple life was over. The manga and anime have gone on for hundreds of episodes, and now we finally get a Live Action Gintama Movie bringing this excellent series to the big screen. It looks like the release date is around July of 2017.
