Fassbinder then gave Lamprecht the lead role of Franz Biberkopf in his acclaimed 1980 miniseries Berlin Alexanderplatz, based on Alfred Döblin's 1929 novel of the same name.

Turner Classic Movies wrote of his performance: "Lamprecht was quite extraordinary as the hapless center of gravity as Biberkopf is drawn into and betrayed by Berlin's underworld in the days spanning from the end of WWI to the Nazi era.

[4][5] Lamprecht's memoirs, And Sadly I'm Still: A Youth in Berlin was published in 2000, where he discusses his experiences in Nazi Germany and the postwar years.
