Animated voice-over roles used to go almost exclusively to performers like the great June Foray, who voiced Rocky the Squirrel and gajillions of other characters in film and TV cartoons over the years. But the success of 'Shrek' suddenly meant that you couldn't sell an animated feature without filling your movie with A-listers like Jack Black and Angelina Jolie, who play two of the key roles in this weekend's new release 'Kung Fu Panda 2: The Kaboom of Doom.'

And while those actors -- as well as co-stars like Dustin Hoffman, Seth Rogen, Lucy Liu, David Cross and Michelle Yeoh -- do exceptional work in the film, casting well-known stars isn't a guarantee that they're going to do justice to talking-animal characters. (Note to producers: The animal characters in 'Tangled' were the best thing in the movie. And they didn't speak.)
