After the collapse of Yugoslavia, during Slobodan Milošević’s regime in the 1990s, Stojanović was a journalist, theatre and documentary film director and anti-war activist.
Belgrade-born Lazar Stojanović became politically active in the early 1960s, and in 1966, he joined the Yugoslav Communist Party from which he was excluded in 1972.
While he was the editor of "Student", Lazar Stojanović published a satirical critique on the Yugoslav political detention camp "Goli otok."
In 1971, this time while being editor of "The Views", he dedicated one issue to the political, legal and press systems of the Third Reich drawing parallels with the Yugoslav communist regime.
The movie remained banned until 1990 in Yugoslavia, and was eventually screened in Belgrade being on the regular repertoire for four months.
[6] Although Plastic Jesus was never screened publicly during Tito’s reign, it was produced at a time in which Party-infighting was calling the Yugoslav regime into question, causing also suppression of artistic freedom.
The "Open University" was a specific form of intellectual oppositional activity, modeled after similar concepts in Czechoslovakia and Poland, and organized as gatherings in private apartments with discussions regarding different topics, including political issues, discussions of historical, philosophical and topics on science.
He seized this opportunity to leave the country and spent the following years in London, Afghanistan, India and Iraq, with several shorter stays in Belgrade.
Lazar Stojanović returned to Serbia in 2011 and worked for the Humanitarian Law Center as Coordinator of the Public Campaign for the Regional Truth Commission project (RECOM).
