Lurtz?

[Sauron the White]

from Legate

Lurtz sounds like a German name, not like an Orcish one

Does not Lugburz also sound German? That is the name that JRRT himself in the books text gives to the Barad-dur as spoken by the orcs. If a German sounding name was considered as authentic by JRRT then it should be darn well acceptable when used by the films. And besides, the name is not Lurtz spoken in the films. Why does anyone care about a name which is not really a name as seen or heard in the films?

I could answer that but it opens up the same old can of worms.
