Violence Jack
The OVA with most censorship problems was "Violence Jack: Evil Town". When Manga Entertainment submitted this OVA to the Australian Office of Film and Literature Classification in 1997, the OVA was refused a rating. It is suspected that this version was the already censored version from the UK (the print reviewed ran 55 mins, whereas the original print runs 60 mins.) Since this OVA was banned, the release of the rest was scrapped.
