I am reading that Fox is recasting all the voices on Futurama to cut costs.
Did you ever see the "new" Jetsons with the different voices?
Does anyone out there like fake Fred Flintstone?
Ever hear a bad Bugs Bunny?
Does Kermit still sound like Kermit to you?
If you can't do it right, don't do it.
Being fair, the producers of Clone Wars did a great job on their voice actors, and I guess Yellow Submarine wasn't too bad.
