Fábri wanted to become an artist from an early age on. He studied painting and graduated at the Hungarian College of Fine Arts. He began working in the Hungarian film industry in 1950 as a production designer. He directed his first film Vihar (Storm) in 1951. He became an internationally acclaimed director with his third feature Körhinta (Merry Go-Round) in 1956. He continued directing and writing until the early 1980s. After his retirement from the film industry Fábri taught on the University of Theatre and Film Arts in Budapest. In his last years he wrote screenplays; they were never made. Fábri was also the president of the Hungarian Film Artist Union from 1959 to 1981.
He was known as a perfectionist who wrote, drawn and choreographed every scene to the most precise detail months before production began and never improvised anything. His reputation as a rigid, tyrannical director was somewhat contradicted by his friendly and kind behaviour towards the British and American child actors on the set of The Boys of Paul Street.
Fábri made nearly all of his films based on literary material (novels or short stories) and wrote the screenplays himself. His constant theme was the question of humanity. Many of his films are set in or around World War II. Two of his frequent collaborators were actress Mari Törőcsik and cinematographer György Illés. In 1969 he played the role of prosecuted statesman Zoltán Dániel in his friend Péter Bacsó's cult satire, A tanú (The Witness) as his sole acting job.
Fábri died in a heart attack at the age of 76 in 1994. His legal successor is Peter Fabri (b. 1985).
