Is film The Order available in Sweden?

If you have the Apple TV app on any of your devices, with a Swedish Apple Account, then you should be able to search for it there. Did you try? What was the result?

It is unfortunately quite difficult to search foreign markets in the modern Apple TV app, so you’ll best ask a Swede this question. It was easier with the iTunes application, where you could browse other countries’ Stores (but not shop there).

It is common for various countries and regions to have different release dates. So it may come at a later date, if it isn’t available there now. That decision is totally up to the distributing studio, Vertical Entertainment or its local representation or licensee.

if you mean the order (2003) then if I search for it on the appletv app on windows I just tried then it's available 

here in denmark, in their itunes store app rent and purchase
