The 1950s was a difficult period for Romanian film, as filmmakers had to give up most of the "conquests" in terms of cinematic language obtained before the end of World War II.
In this climate, Marcus made a number of comedy films of lesser value, such as such as I do Not Want to Get Married (1960) and The District of Joy (1964).
The 1969 movie, which talks about the price of freedom of political underground mission, pursued by the authorities, and whose soundtrack is between the Phoenix band's tracks, was banned in the early 1970s.
The climax of his artistic career came at a time when it was hard to tell the truth easily, as freedom of expression was restricted (see Censorship in Communist Romania).
In the 1970s, Marcus made two films which were greatly appreciated by the public and by critics: The Actor and the Savages (1974) and Operation Monster [ro] (1976), a drama and a comedy which sometimes fail to convey emotions through subliminal messages powerful, to make characters.
