<Li> Jane Lynch as Alice, a Canada goose who is Chloe's sister . </Li> <P> Saldanha first had the idea for the film in 1995, involving a penguin being washed up on the beaches of Ipanema; it was changed to the current story after he learned of Happy Feet and Surf's Up (two other films involving penguins) being produced . 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 . </P> <P> 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 . Eisenberg was asked during the filming of The Social Network if he would do his voice recording on the weekends, and he agreed after reading the script, saying: "It was the perfect antidote to get out of the mindset of my character in Social Network who was so severe, and in some ways so joyless ." </P> <P> For music, they brought on board Sérgio Mendes to act as music guru and online living library . He in turn was able to reach out to artists such as will.i.am and Carlinhos Brown to provide music for the film . </P>
