not banned,post review wrong I think.

The first person to review this film suggests that this film was restricted for viewing due to its subject matter.
I had never heard this suggested before,certainly I saw it in a art cinema in the early 1980s and it has been on tv at some point.
I don't think it was banned but it is true it is not well known,perhaps because it is a black and white film and not very pact but I think it is a great film.
