Following the behemoth of Ice Age 3: Dawn of the Dinosaurs ($880m in receipts and counting), the next 3D digital animation from Fox is set to be Rio. Anne Hathaway and Neil Patrick Harris are in negotiations for voice duties, and the director will once again be Carlos Saldanha. The story is not about Hathaway dancing on the sand, just like a river twisting through a dusty land, but a "nerdy mccaw" who escapes from his cage in Minnesota and heads south for some fun in the sun. Rodrigo Santoro (Xerxes in 300) is also in talks for a role. Harris, who also provided a voice for Cloudy With a Chance of Meatballs, is doing rather well for himself lately, what with his ongoing series How I Met Your Mother, the Harold and Kumar appearances, and the awesome Doctor Horrible's Singalong Blog. It would almost be possible to forget that he was once Doogie Howser MD, except that people keep mentioning it. Rio is aiming for an April 2011 release. We'll bring you more on who's playing what as we get it. |
