Ryan Reynolds, Nicolas Cage voice "Croods" cartoon

LOS ANGELES (Hollywood Reporter) - Ryan Reynolds and Nicolas Cage are taking the lead voice roles in the DreamWorks Animation feature "The Croods."

Chris Sanders ("Lilo & Stitch") is directing a screenplay from Kirk DeMicco ("Space Chimps") and Monty Python icon John Cleese.

In the story, an earthquake forces caveman Grug (Cage) and his family into the wider prehistoric world looking for a new home, a situation complicated when they encounter a mysterious nomad (Reynolds). As the stranger introduces the family to the concept of "tomorrow," it stirs conflict with Grug's reliance on tradition, especially when Grug's eldest daughter becomes smitten with more than the nomad's ideas.

The film, originally announced at the Cannes Film Festival in 2005, is set for release March 30, 2012; DreamWorks Animation also has "Madagascar 3" (May 25) and "The Guardians" (November 2) set for release that year.

All three will be in 3D.

Reynolds next will shoot the superhero film "Green Lantern," set for release in June 2011. He most recently starred in "X-Men Origins: Wolverine" and "The Proposal." He next appears in the thriller "Buried."

Cage recently has done voices for the animated films "G-Force," "Astro Boy" and "The Ant Bully." He next appears in the Lionsgate actioner "Kick-Ass," which will premiere next month at the South by Southwest Film Festival in Texas.
