Okay, so let's just run down the roster here, shall we? The Princess and the Frog had Oprah Winfrey, Terrence Howard, and John Goodman doing voices. This week's How to Train Your Dragon will offer Jay Baruchel, Craig Ferguson, America Ferrera, and Jonah Hill. Toy Story 3 has Tom Hanks and Tim Allen, natch, plus Michael Keaton, Joan Cusack, Bonnie Hunt ... and others too numerous to mention. And that's just a handful of recent releases -- go back over the decades and you'll see how rapidly animated movies have become the domain of legitimate actors.
And that's okay by us. Aside from triggering an audience's "Hey, it's..." reaction when a celebrated voice is heard, letting an established star loose in a cartoon can bring a level of depth and nuance to creatures who are frequently little more than drawn scribbles or computer constructs.

Here, then, is our list of 10 stars who might fare better with a permanent move to Toontown, now with double the movie clips!
