Behind the scenes
The word "Exterminieren", which the German-speaking Daleks used, is not in common use. In the German dubs of the episodes, the word used is "Vernichten" (literally, "Reduce to nothing"; colloquially, "Destroy"). The full dialogue for the German Daleks is as follows: "Exterminieren! Exterminieren! Halt! Sonst werden wir Sie exterminieren! Sie sind jetzt ein Gefangener der Daleks! Exterminieren! Exterminieren!" This translates as: "Exterminate! Exterminate! Stop! Or we will exterminate you. You are now a prisoner of the Daleks. Exterminate! Exterminate!"
