Movies from the Apple TV Store (a.k.a. “iTunes Store”) will list the Original Audio Language and the included Audio Language separately. See the Languages header. Original Audio Language is not necessarily included; if it is, then it will be listed among the included Audio Languages as well.
Some movies with multiple language editions might be sold as separate store items. This can differ by country. Find out by scrolling down to How to Watch, where all available editions will be listed. In such cases, your purchase is only valid for one edition.
If you accidentally purchased the wrong language edition, then you may contact the iTunes Store staff, to help correct that, by undoing the last purchase, and getting the wanted edition instead. Else consider asking for a refund. Don’t wait too long, else the purchase is permanent and the correction can’t be done anymore.
For the US for this title, one audio track is included, when purchased through Apple: English only.
It does not appear to have multiple language editions there.
