Convention/Your Name movie
I will preface this by saying I don't know if this is the right place to post and if not I'm sure it will get directed to the right place. Nonetheless, I go to Anime Detour each year, and this year is no different. Presuming that Funimation will once again be there, I will like to see if there is a way for the Your Name movie to be screened at the convention. April 7th is the first date of the convention and I'm sure tons of fans would be happy to screen it there versus having to travel to a nearby theater. I'm only speaking on my behalf but I figured at the very least I could open up a dialogue and see if this was a possibility.
You should talk to the organizers of the this particular con, as they ones who would assume financial/management responsibilities; barring a FUNInitative for some reason.
But yes in general as to anime conventions: Showing something people actually want to watch for once, would make marketing sense, in either case .
