The producer said in an interview there’s plans to screen the movie in around 50 countries after the Japan release, although there’s no mention which ones. So maybe do check regularly on your local cinema especially if they’ve showed anime/japanese movies before.

I mean he /did/ save him along with Saeki in episode 9... But seems his heart failed again after a year, and Amagi decided to tell no one... That's how I see it
