Wong Language rented movie
I rented a movie that has the original audio in english, but because I live in Switzerland, it came in german without the original language option. I don’t speak german.
Question marked as
Each movie in the iTunes Store for each country or region, lists the included languages (audio and subtitles) for each title, so that you can make an informed buying/renting decision. Original audio isn’t mandatory.
When multiple (often two) audio streams are included, then you can switch to your preferred one. Change subtitles or languages for videos in the Apple TV app or iTunes Store - Apple Support
What movie title did you want to watch?
If you want to undo the purchase for this reason, then request that with the Store staff.
