There was a fairly decent film on the Baader-Meinhof Group that was done in the last few years. It is a german film, so you’ll have to either read subtitles or brush-up on your Deutsch.
That was a good movie.
I was never worried about the ultra left until I saw Baader_Meinhof Complex.
Anyone who thinks Libs shoot like Barney Fief needs to see this film
