A: This is highly unlikely. English dubbing is a very expensive process typically reserved for major international releases or popular anime. An obscure 2001 German TV movie would be a very unlikely candidate for an English dub.

This is the method most likely to yield success. Your mission is to track down a physical copy of the film that lists English subtitles.
