@willhbr I think I have enough wiki cred but when I tried to look into this I just got myself a bit confused. It seems like parts of the film were filmed in both Norway and New Zealand. (whether the cited source says what is in the article is, of course, a consideration but there are others such as whether other sources should be cited in addition to or instead of that one). I put my findings in a comment under "New Zealand or Norway?" at https://en.wikipedia.org/wiki/Talk:Siachen_Glacier
