Most of the complaints were around Klaus Maria Brandauer as Pascal sounding like he just phoned in his lines. I’m not German but even I can tell his delivery sounds really flat.
Dolby SR is supposed to work with prologic theater sound systems so I’m guessing it’s either a conversion from prologic surround to discreet 5.1 or something modified off of that. I might do a prologic-style upmix of the German track on the Deaf Crocodile release to see how it compares to the mix from the DVD.
There’s a spot on the DVD where you can see instructions to the animators, in English, at the end of the scroll of names on the computer screen. Something like this wouldn’t have made it to the final film. The animation utilized animation studios in both Germany and Canada so the English instructions imply that the computer screen animation was probably done in Canada. I believe the Deaf Crocodile release is what was actually seen in German theaters since they used the original negatives and the opening titles are in German. The screens scroll by so fast that the viewer was never expected to actually read them but they were replaced with alternate animation in German for the DVD since the viewers could now pause the video. The computer scroll has some funny little jokes thrown in by the animators, as well.
It’s interesting that the end credits are in English on both the DVD and UHD Bluray release. This could indicate that they were hoping for an international release that never really happened.
I found the correct list of voice actors for the English dub:
Francis - Jeff Harding
Bluebeard - Graydon Gould
Claudandus/Pascal - Peter Marinker
Jesaja/Isaiah - Ian Tyler
Kong - Bob Sessions
Julius Preterius - Don Fellows
Joker - William Roberts
Felicity - Tamsin Hollo
Gustav Löbel/Gus - Marc Smith
Archie - Peter Whitman (unverified)
Nhozemphtekh - Liza Ross
Gregor Mendel - Marc Smith
Pepeline - (unknown, possibly Liza Ross)
The English dub was probably sort of a scratch track. If the movie had been picked up for a proper international release, they would have hired a few well-known actors to re-dub some of the characters voices the way the did with the German version
There is also a French dub that I don’t have.
