In 1977 WDR broadcast a German adaptation of the radio play by Howard Koch and the translation by Robert Schnor . The US-American production was partly retained in the original and translated by German speakers in the so-called voice-over process . Under the direction of Klaus Schöning spoke:
Eva Garg : Spokeswoman
Jürgen Thormann : Orson Welles / Professor Pierson
Christian Brückner : Carl Philipps
Gert Haucke : Stranger
Robert Seibert : Mr. Wilmuth / General Smith / Captain Lansing / Minister / Captain Vote / Radio Operator / Radio Amateur
The well-known German radio journalists Dieter Thoma and Lothar Dombrowski acted as moderators and announcers in the studio, apparently bringing real news about the invasion. Despite the numerous references to the fictional character and despite the clearly audible age of the original recording, there were many worried calls at the first broadcast.
