Dan chooses to work on the land, living in a kibbutz in the South of Israel. Aaron, his brother is a doctor of law and philosophy and a distinguished scholar of the Torah. He comes to Jerusalem from the United States to defend the rights of Torah students. The conflict which arises between the two brothers reflects that of a society torn between its religious and political principles. With restrictions on the increase and injustices multiplying, Israel today is on the brink of civil war. This film opens a subtle yet essential debate on the question of separation of the state and religion in Israel.
After having lived between 1948 and 1959 in a kibbutz in Israel, he worked as a cameraman in Tel Aviv before returning to Switzerland in 1964 to work for the Television Suisse Romande. From 1968 onwards, he worked for the production company Telvetia.
Igaal Niddam followed that achievement with the Third cry presented in 1974. The film, co-written with Yves Navarre and Marguerite Cassan, received the award for best screenplay at the festival of Sitges. He returns to the cinema in 2008 with Dan and Aaron (Brothers).
