Anonymous sources claim actor Shun Oguri will start in a movie scheduled for release in 2018
Following rapidly on the heels of rumors of a live-action film adaptation of JoJo's Bizarre Adventure, the latest Weekly Shōnen Jump manga / TV anime to receive a translation from the comic panel / TV tube to the silver screen is Gintama, or at least that's what anonymous sources on the Internet would have you believe.

Japanese fan site Otapol is reporting that (according to unnamed official sources close to the production), a live-action Gintama film starring actor Shun Oguri (who starred in the 2016 live-action TerraFormars film and the 2014 live-action Lupin III film) as Gintoki Sakata is currently in the works. The project is allegedly shooting for a release date in 2018.

Like most rumors related to live-action adaptations in general and Gintama in particular, I'd take this one with a boulder-sized grain of salt until more concrete information can be obtained.
