Ivan Passer was one of the key authors of the "new wave" of Czech cinema, a group of young people who forged an energetic and transgressive film movement in the 1960s, breaking away from the precepts of hard socialist realism. Passer was not only the author of the scenarios of his own films, but he also worked on the scripts of the first four motion pictures made by his countryman, friend and colleague Milos Forman: "Konkurs" (1963), "Black Petr" ( 1964), "Loves of a Blonde" (1965) and "The Firemen's Ball" (1967).

Passer was born in Prague, the son of Marianna (Mandelíková) and Alois Passer. He was the grandson of a silent movie screenwriter. Ivan's parents were persecuted by the Nazis for their Jewish heritage. Ivan was a rebel boy, sent to a boarding school where he became friends with Milos. Together they went to study cinema at the FAMU film school in Prague, but young Ivan was eventually expelled from the academy. By then he had acquired skills in movie-making, some experience and had key friends, such as cinematographer Miroslav Ondricek. With Forman and other friends, they made their first movies.

In 1965 Passer made a remarkable first feature, the beautiful "Intimate Lighting", a film of impressionist inspiration that immediately established his name as a promising new director. But the social pressures and political unrest in Czechoslovakia, which culminated in 1968 with the Soviet invasion, led him into exile the following year. However, in the United States he did not achieve the notoriety of Forman, who received the best proposals, while he rejected offers that did not convince him: for example, he refused to make "Yentl" for a number of reasons, including his conviction that Barbra Streisand was too old and famous for the role, in opposition to other key performers as Mandy Patinkin and Amy Irving. Likewise, he refused to make films with elements of violence, which he always opposed. During World War II he had been directly exposed to violence, and he believed that it was dangerous to represent it in films: violence, he said, affects "some people who are not able to realize the difference between reality and fantasy."

However, he made some worthy movies, such as his American debut "Born to Win" (1971), a complex portrait of a heroin-addict hairdresser; his satire on civil surveillance, "Law and Disorder" (1974); the comedy about money-laundering bankers "Silver Bears" (1977), and the cult film "Cutter's Way" (1981), in which a war veteran investigates a crime, despite he only has one eye, one arm and one leg. For television he directed the biopic "Stalin" in 1992.

Passer taught film at the University of Southern California, and lectured students in foreign film academies. He died in Reno, Nevada, on January 9, 2020.
