More about the nudity in Tatort

Tatort has been going since 1970, that’s fifty six years. Lots of famous German actresses have got naked on it, including Nastassja Kinski when she was only sixteen years old.
It also had at least one spin-off series, Schimanski, which also had nudity and lasted over a decade.
