I found this film at Youtube: http://www.youtube.com/watch?v=-G-mbmZb ... r_embedded
The film "Weltraumschiff 1 startet" (Spaceship 1 is starting) has been produced in 1937 for the German television. It had been shown in German TV in 1938. So you have the chance to see a really strange piece of German prewar television. (Of course in German, sorry, no subtitles.)
