Anne Hathaway, Neil Patrick Harris and Rodrigo Santoro are negotiating to lend their voices to "Rio," the next collaboration between Blue Sky Studios, Fox Animation and director Carlos Saldanha; the team behind the $882 million grossing "Ice Age: Dawn of the Dinosaurs."
"Rio" follows the adventures of a nerdy macaw who lights out from his small-town Minnesota cage for the Summer Olympic city of Rio de Janeiro.
