Aleksandar "Saša" Petrović was a Serbian film director. He was 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 in 1967. The latter 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 and the Grand Prize of the Jury at the Cannes Film Festival; it also received a nomination for a Golden Globe. In 1967 Petrović was a member of the jury at the 17th Berlin International Film Festival.
