The original title was "Manchete de Jornal" (Newspaper Headline). The new title, which in English means "World - Sex Market", was chosen for market reasons, at a time when erotic films were very successful in Brazilian theaters.
Mojica's mother Carmen Marins and daughter Liz Marins made small cameos, and his son Crounel Marins worked as assistant director.
The project was filmed and hurriedly completed as a kind of compensation for Mojica's troupe: all the money that the film recovered at the box office would be shared between them and the director wouldn't earn a cent; in return, everyone would work for free in his new film, Estupro (1979).
José Mojica Marins conceived the idea at least two decades earlier, inspired by his personal rivalry with a journalist. In 1953, when 18-year-old Mojica was preparing his first feature film, he suffered a smear campaign by a São Paulo newspaper. The director tried to get all the copies of the edition that said bad things about his work, but buying hundreds of copies ended up motivating a second print run of the newspaper.
This was the last genre film directed by and starring José Mojica Marins to reach theaters until A Encarnação do Demônio (2008), almost 30 years later. In the meantime, Mojica made only pornographic films and direct-to-video productions, as well as special guest appearances in movies directed by friends.
