Hello, Hello, Carnival was the first Brazilian film to use playback in the production of its musical numbers. Limiting this process to only a few choice scenes, direct live audio can still be heard in the background.[1]
Originally called "O Grande Cassino", the film's inception came from the need to present singers from Brazil's golden age of radio to a larger mass audience. Set in a pre-television age, the plot focuses on a low-income population which had little, if any, access to entertainment at the nation's Casinos.
Restoration
The film has been restored several times. In 1952, a print was given to the Cooperativa Cinematográfica Brasileira, where it was remounted, removing several scenes. Another restoration was made in 1974, reversing these deletions. In 1986, scenes with comedian Jorge Murad were found in the film library of the Museum of Modern Art, Rio de Janeiro. By the end of 2000, a serious quality restoration project began with substantial financial support. The team concluded its work in March 2002.[2] The film was rereleased in São Paulo, in June 2002.[3]
