Voices

I'm watching this because it was on after Clone Wars on cartoon network and I'm too lazy to get up and change the channel while I'm wasting time on my computer. I've heard a Ton of voices on this. Was it a labor of love for some or did they owe the producers a favor or did the acting budget actually have the kind of pay to pull in all the big names?
Saget - Dudes LOADED. Why would he be in it?
Belushi - Gotta be the paycheck on his part.
John DiMaggio - I think he's contractually obligated to be the voice in EVERYTHING lately.
Billy West - Probably just caught a ride in with DiMaggio.
Maurice Lamarche - Gas money is much cheaper in LA when split 3 ways.
Castellaneta - Yeah, this has to be a favor to someone. I think I have to pay him just for using his name in this post, with as much scratch as he commands.


PS - The Zombie girl is pretty funny. I like how no one in the horror world likes Zombies, nice to see an allegorical prejudice make its way into a kiddy story.
