I feel like I'm in the majority here, but, even if an English Gintama Movie 2 was released, I would stick with the japanese version (which would have to be consumed through fansubs since I don't understand japanese). The truth is I absolutely LOVE the japanese voice actors in Gintama, as well as most animes in general, but Gintama japanese voice actors are simply the best. That said, if there was an english version released, I would probably have to buy it at some point to show support for the series and for Sunrise/Sorachi. I feel as though, by consuming it through a fansub but still buying the english version to show support would be the best thing I can do. That said, I am not particularly interested in an english dubbed version for myself, though I do think it would be great to have in general.
