Montblack,

Is this the film? Dad always liked this one, when it came on TV.
http://www.imdb.com/title/tt0055256/
One, Two, Three (1961)

Yep, that's the one. Couldn't imagine that the title was translated to German
literally, so I didn't dare translate it back.

Speaking of German born Directors...

Well, as with so many German scientists, artists et cetera working in the US,
they were mostly of course Jews that had fled Germany because of the Nazis.
The intellectual loss to Germany was immense, of course. The Barbarians ruled.
And the majority of Germans supported them. Sad.
