Maziar Bahari, the Iranian film-maker who worked with Jane Corbin on the Panorama film Obama and the Ayatollah that ran before last month's fateful elections, was arrested in Tehran on 21 June. His laptop and some video tapes were also taken by men who didn't identify themselves.
Reliable information is hard to come by but to the best of our knowledge he is in Evin prison and a "confession" attributed to him has been released in which he was described as a "collaborator of British and American media" who had compiled "hostile and false" reports.
Maziar, who has dual Canadian nationality, is an independent film-maker who also works for a wide range of broadcasters and publications. He wasn't working for the BBC in the period after the elections when the country was gripped by demonstrations and widespread allegations that the election had been rigged in favour of President Mahmoud Ahmadinejad .
Maziar's contributions to Panorama would themselves have caused little complaint in Tehran. He worked on a 2008 film critical of the actions of the British Army in southern Iraq On Whose Orders? and as Jane Corbin points out anyone wanting a cliched and one-sided view of Iran would be wasting their time approaching Maziar.
"When I worked with Maziar in Tehran, I was able to appreciate how an experienced Iranian film-maker and journalist sees situations in his own country which the Western media and governments do not always appreciate or understand. We went to Shiraz to film where 14 people had been killed last year in a bomb attack by an anti-government group.
I was able to understand, through Maziar's explanations and translations of the views of people there, that while the West regards Iran as a perpetrator of terror, Iranians often see themselves as the victims of terror.
The deputy prosecutor of Tehran showed us documents, arrest warrants from Interpol, detailing how some of those associated with the group behind the crime were believed to be living freely in the UK and US. Maziar felt this was a very important story and I am glad we covered it.
Maziar was always very keen to explain to me the Iranian government's view of the political, social and economic situation inside the country.
We spent equal time covering the campaigns of President Ahmadinejad and Mir Hosein Mousavi. As a journalist, Maziar was only concerned with covering the issues and views of other people, not to let any personal preference become part of the story we were covering. He was always respectful and appreciative at all times of the achievements of the Islamic Republic of Iran and the contributions made by all sectors of Iranian society."
Maziar is a film-maker in his own right, with at least 10 films to his credit, and a playwright. His movie, And Along Came a Spider, was the first Iranian documentary to be aired on HBO in the US. He is active in the Iranian Documentary Film-makers Association, and has worked closely with young Iranians who aspire to be film-makers. Two years ago the International Documentary Film Festival in Amsterdam organised a retrospective of his work.
He is also one of the few film-makers to work in Iraq since the US invasion in 2003. His films have covered subjects as varied as Grand Ayatollah Ali Sistani and Shia cleric Moqtada al-Sadr, and his work on the difficulties faced by journalists in Iraq has been especially well regarded.
The Harvard Film Archives had this to say about his work:
"In a country known for neorealist fiction films that focus on small events in the lives of individuals, the work of Iranian director Maziar Bahari is somewhat anomalous. Employing a traditional documentary style to explore more far-reaching cultural events, Bahari's films provide a glimpse inside contemporary Iranian culture as they reveal the human element behind the headlines and capture cultural truths through the lens of individual experience.
Representing a new generation of young Iranian film-makers, Bahari's trenchant looks at social issues in his country have brought both controversy and international acclaim."
