THIS was the movie they blew the budget on as far as hiring celebrity voice actors, THIS movie. This movie had more celebrity voices than Over The Hedge, Rio 2 and How to Train your dragon COMBINED. THIS was their movie they needed an all star cast for. If they'd waited a few years they could've gotten Cuba Gooding Jr at bargain basement prices, but this was during a time when he cost more than Robert Down Jr in Iron Man, even though he was the lead!
It's mindblowing they thought this was such an important movie they had to go all out for the celebrities and somehow it still managed to be cheaper than Chicken Little what the actual fuck
