He wrote films including Ucho, Fetters, Slasti Otce vlasti and On the Comet.

Procházka was also involved in films such as A Report on the Party and the Guests and Diamonds of the Night.

He studied at the Higher Agricultural School in Olomouc and after graduation, he began working in the border areas as the head of the State Youth Farm on the Stavovské panství Bruntál (1945–1949).

He assisted Bohumil Hrabal, Arnošt Lustig, and was behind the creation of films such as "Diamonds of the Night" or "Daisies", even though he was not close to the poetics of Vera Chytilová, but "as an artist, she has the right to speak," he said.
