He pitched the idea to Chris Wedge at Blue Sky in 2006. Saldanha showed the animators maps and books with geographic landmarks and measurements, from which they built a digital version of Rio. Later, a group of artists from the company visited Rio to see the various story locations. The animators also met with an expert on macaws at the Bronx Zoo to gain insight into their movement and personalities. Saldanha himself is a Brazilian from Rio de Janeiro; such elements of Brazilian culture and landmarks were also influenced from Saldanha growing up in Brazil. The lead voice actors were approached in 2009. Jemaine Clement was approached to do the film after seeing test shots of his character Nigel doing a speech from Flight of the Conchords, which was done prior to a script being finalized. Neil Patrick Harris was supposed to voice Blu, but had other commitments outside production; he was later replaced by Jesse Eisenberg.

He in turn was able to reach out to artists such as will.i.am and Carlinhos Brown to provide music for the film.

Hathaway stated in an interview that she didn't see Eisenberg during production of Rio except "socially throughout the process," but that she was "very happy for all of his success."
