Anne Hathaway and Neil Patrick Harris will lend their voices for "Rio"

Anne Hathaway and Neil Patrick Harris are in the negotiating tables to lend their services as voices in the new animated film "Rio". Rodrigo Santoro also thinking to hop in.

"Rio," the next collaboration between Blue Sky Studios, Fox Animation and director Carlos Saldanha, all of whom are riding the $882 million global tsunami of "Ice Age: Dawn of the Dinosaurs."

"Rio," which 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, is scheduled for an April 8, 2011, release. Like "Dinosaurs," it will be filmed in 3D digital animation. -THR

It will be great casting choice especially using the expressive voice of Neil Patrick Harris.
