I remember watching this - presumably all however-many-hours (26?!) -it-was - on BBC2 as a teenager who had just started learning German. How I long for it to be repeated again. It was a great (though obviously not a commercial) success here in Britain, thanks to the Beeb. Sadly the German public state broadcaster, Westdeutscher Rundfunk (WDR), which funded Die Zweite Heimat, chose to relegate it to a very late night slot when it was premiered, so in its own country it is less well known.
Meanwhile, though, if you can read German, try and get a copy of the screenplay. A massive hardback, to read the scripts and directions is just as engrossing as watching the films themselves - and there's some lovely colour and black-and-white stills too.
And if you haven't seen Heimat, the prequel, do so too!
