Nikolai Rozantsev directed the movie Zagovor Poslov after the original director, Boris Barnet, who already started pre-production, but unexpectedly committed suicide at age 62 in Riga, USSR [now Latvia].
Nikolai Rozantsev was under heavy political pressure in the Soviet Union; he was censored and then restricted by the Soviet government to making only black-and-white films.
Nikolai Rozantsev was censored by the Soviet government and his film Razvyazka (1969) was labeled as "Anti-Soviet" so the original director's version of the movie was destroyed.
