Schulhoff directed several short films before his feature film debut with the detective film Strach (1963). Afterwards, he made The Murderer Hides His Face (Vrah skryvá tvár, 1966) and Po stopách krve (1969), which together with the two previous films makes sort of a trilogy of criminal films with Rudolf Hrusínský as detective Kalas. He directed many TV films and afterwards two more criminal films Vim, ze jsi vrah (1971) and Osud jménem Kamila (1974). He also tried out himself in the genre of comedy with Hodíme se k sobe, milácku..? (1974), Zítra roztocíme, drahousku... (1976), 'Já to tedy beru, séfe..!' (1977), Já uz budu hodný, dedecku! (1979), Co je doma, to se pocítá, pánové... (1980) and Príste budeme chytrejsí, starousku! (1982). He returned to his character of inspector Kalas in the film Diagnóza smrti (1979).
