I guess that spoils about the only plot twist in the movie for anyone who speaks German....
SPOILER ALERT
The villain, Dr. Deadhead, is actually dead since 20 years before the movie begins, with his operation being run by his android daughter, and all one ever sees is his head, Twice in a photograph, In a Video, and the coolest of all, as an electrically projected image suspended betwen two Tesla coils.
End of Spoiler...
