Allen hasn't taken Paes up on his offer, but the mayor continues to lobby hard. Scoring a film by the legendary director would help cement Paes' vision for the city: to turn Rio into a cinema hub, the Los Angeles of South America.
While Hollywood needn't watch its back just yet, there's no doubt that Brazil's film industry is booming, as the Rio film festival that runs through Oct. 10 puts on display.
The country is on track to make 100 feature films this year, up from 30 in 2003, and it's increasingly sought out by foreign productions cashing in on the government's generous subsidies and incentives. New studio complexes are in the works, and cinemas are mushrooming across Brazil to keep pace with ever-growing numbers of movie-goers, many of them new members of the middle class who were pulled out of poverty by a decade of booming economic growth.
"The big shift is that now many more people have disposable income," said Adrien Muselet, chief operating officer of RioFilme, the city government's film finance company. "Once you've covered your basic necessities, bought your fridge and your washing machine, what do you want next? Fun. And for many people, that means the movies."
The new viewers have helped push Brazil's box office gross from $327 million in 2008 to $737 million last year, according to the trade publication Filme B. That puts Brazil among the top 10 movie consuming countries in the world, said Muselet, and the industry is taking note.
With its population of 204 million, this South American giant is increasingly factoring into the major United States studios' strategic calculations.
"When you take an American blockbuster and you set it here in Brazil, even for just a couple of scenes, it just explodes in the box office here," said Muselet, pointing to "Breaking Dawn," part of the "Twilight" series of teen vampire movies, which was filmed partially on location in Rio and the coastal colonial city of Paraty. Brazilians flocked to the movie, and the country ended up being the film's second biggest market.
Other big Hollywood productions such as "Fast Five" of the "Fast and Furious" franchise and the Sylvester Stallone vehicle "The Expendables" were also partially shot here in recent years. "Billy Elliot" director Stephen Daldry's "Trash" is currently rolling.
Rio officials also hope movies made here will help burnish the image of a city mostly notorious for its grinding poverty and drug-fueled violence, particularly as Rio gears up to host next year's soccer World Cup and the 2016 Olympics.
In a bid to attract more foreign productions, Rio's state government created an agency to walk teams through Brazil's Byzantine bureaucracy, helping them get the dizzying number of permits and permissions needed to shoot. The Rio Film Commission also hopes to increasingly help foreign productions find Brazilian investors, allowing them to qualify for the government subsidies and incentives that make up the lion's share of practically all movie budgets here.
Producer Aaron Berger, an American who works in both Rio and Los Angeles, said the subsidies helped get things rolling for his series "Gaby Estrela," which is about to premier on Globo TV's kids cable channel Gloob. "It was a tremendous boost for us," he said.
Over the past decade, the federal government has spent more than $450 million on films, and many state and city governments also invest in movies made locally, provided they meet requirements that typically include hiring at least a certain number of local employees. And since Brazilian law allows corporate tax write-offs for cultural projects, companies such as petroleum giant Petrobras and cellphone provider Claro often underwrite movies.
Brazilian films have made inroads internationally in the last five years, notably the "Elite Squad" films probing gang violence and political corruption in Rio. Other domestic fare includes smart comedies and smaller budget films aimed at the art-house circuit.
The industry also got a boost from a 2011 law requiring all cable television channels to show at least 3 1/2 hours of independently produced local content each week during prime time.
"All of a sudden there's a huge demand for this sort of content," said Steve Solot, president of the Latin American Training Center, a Rio-based audiovisual consultancy. "It's a fantastic new market."
The industry's sudden growth has caused shortages of qualified technicians, such as electricians, camera operators and sound people, and RioFilme is scrambling to fill the gap through training courses.
"We wouldn't be seeing this kind of shortage if there weren't a lot of demand," said the agency's president, Sergio Sa Leitao. "In a strange way, it's a really good thing."
