Aleksandar Petrović (14 January 1929 – 20 August 1994) was a Yugoslav and Serbian film director who was one of the leading European directors in the 1960s and one of the major figures of the Yugoslav Black Wave. Two of his films were nominated for the Academy Award for Best Foreign Language Film: Three in 1966 and I Even Met Happy Gypsies (Feather Gatherers) in 1967. The latter (original title "Skupljaci perja") was the first movie that presented the existence of Gypsies in society and everyday life; it was also the first full-feature film where Gypsies spoke their own language, Roma. Most roles were interpreted by real Gypsies; this was their movie. "As a child, I observed them and saw in these people faith and irrationality," said Petrović I Even Met Happy Gypsies won the FIPRESCI Prize
