Superb drama - DVD release please!

An excellent and compelling drama - I just could not take my eyes off it! A valuable dramatisation of a real historical event that makes you feel you are there watching it unfold before your eyes. It shows the (foolhardy?) courage of Litten in challenging Hitler, but also helps to portray the commanding presence of Hitler. He is clearly a man who is in charge, seeming to dominate everyone - and by the end of the proceedings he seems to be in command of the Court - the implication being that he has convinced the Judge that he will be in power in the near future and the Judge begins to feel that if he wants a future in the legal profession he had better start siding with Hitler as much as he can....... By the end, the public gallery and even the journalists are shouting Heil Hitler!
It would be interesting to know what is drama and what is historical fact in this dramatisation - worthy of further research I think.
