The film, produced by Factum Film from Zagreb and Television B92 from Belgrade, was shown at the Zagreb Film Festival.
The film features testimonies by some 15 former prison inmates from Serbia and Montenegro and Bosnia-Herzegovina about torture and murders in the prison, as well as interviews with Croatian generals and military police officials from Split County, legal experts, journalists and a former Austrian parliamentary deputy.
The film describes the situation in Croatia and Split in 1991, the POW exchange in Nemetin in 1992, and the first trial for war crimes committed at Lora in 2002.
Puhovski said that it was difficult to establish contact with the witnesses as they were deeply traumatised, but that they were willing to come to Croatia and testify if given minimal security guarantees.
He said that he would offer the film to Croatian Television despite previous negative experience with the showing of similar movies.
Milorad Pupovac, an MP and vice-president of the Independent Democratic Serb Party (SDSS), said that the documentary was objective and balanced.
Libra party leader Jozo Rados also attended the showing of the film.
Asked why two police officers were placed at the entrance to the theatre, Puhovski said that the organisers of the festival informed him that they had received threats from a war veterans' group.
