Yes, because Tim Allen (back in the 90's), Tom Hanks, Ed Asner, Owen Wilson, and Larry the Cable Guy are "guys that happened to be in the office."
Pixar casts actors who'd you'd cast if the film was a live action version.
Ed Asner played an animated Ed Asner. You could easily see Cars remade live with Owen Wilson and Larry.
Tom & Tim aren't as personally connect to their rolls as in others, but Dave Foley and Julia Louis Dryfus? Monsters Inc works just as well if you point a camera at John Goodman and Billy Crystal.
What did America Ferrara, Jonah Hill or Kristin Wiig bring of themselves to Dragon?
Or generic voiced Reese Witherspoon, Seth Rogan, or Rain Wilson to Monsters vs Alien. Colbert played an exagerated version of his own character, and at least Hugh Laurie went nuts with the role to justify his casting.
(and yes, Resse Withspoon would actually play that part in a live action..as would Amy Adams, Rachel McAdams, and Jennifer Aniston. IE. Generic leading lady, so you might as well have cast Tara Strong, and save some money to be used for the script (and get a better voice performance))
