Obviously it can be described as that, as that is what it is.
It is, however, made by an American studio with heavy interest from a major American star with a personal interest in WWII. Tom Hanks wanting to make the film is enough for it to happen, by some studio at least.
We have film studios in the U.K.? Thank you for pointing that out to me, I was obviously completely unaware of this simple fact.
My point was, however, there doesn’t seem to be the will, or public interest, for it to happen in the U.K.
Outside of some smaller budget efforts, I can’t think of any ‘proper’ WWII films made in the last decade or so. A naval warfare film in particular requires a hefty budget.
