The Spanish Castilian dubbing was made based on the English dubbing. Some of the supporting characters names were kept on their English version and the money is mentioned in Dollars on in Marks.
The Spanish Castilian VHS/BETA cover Dieter Hallervorden's name does not appear.
The original German version features the title song "Didi - Der Doppelgänger" sung by Dieter Hallervorden over the end credits. For the English and French dubbed versions this was changed, here an instrumental version was used instead.
