Anne Hathaway, Neil Patrick Harris and Rodrigo Santoro are in talks to voice the animated feature Rio, for Blue Sky Studios, Fox Animation and director Carlos Saldanha, who also teamed up for Ice Age: Dawn of the Dinosaurs.
According to The Hollywood Reporter, Rio follows the adventures of a nerdy macaw who lights out from his small-town Minnesota cage for the exotic Summer Olympic city of Rio de Janeiro. Like "Dinosaurs," it will be filmed in 3D digital animation.
Hathaway and Harris have done animation before. Hathaway voiced the lead role of Red in the Weinstein Co. release Hoodwinked in 2005, and Harris voiced a character in Sony Pictures Animation's Cloudy with a Chance of Meatballs.
Fox would not confirm casting.
Rio is scheduled for an April 8, 2011 release.
