JackBlack and KungFu Panda on the Red Carpet

he looks a lot like him!

He does look a lot like him! Is it possible that they picked Jack Black first and then animated the character?!?!

I think that they often create the character around the actor who does the voice. Look at Marty from Madagascar ... he looks JUST like Chris Rock!!

yes beacause he is fat

yes

i agree that JB and Po are very similar in appearance, but that's the point isn't it? if you've seen any other films JB has been in (the Pick of Destiny rocked out!) and notice the facial expressions and body movement, the animators completely hit the nail on the head! i especially liked the few lines in KungFu Panda where JB remarks about the "Trident of Destiny" and "bringing the thunder." both of those were from Pick of Destiny. i've watched JB's career continue to grow... he was in Mars Attacks, and the Jackal (where he got killed in both!) Enemy of the State, Be Kind Rewind, King Kong... etc. he deserves to do well! You Can't Kill The Metal!!

he actuly does its pretty cool

They put a lot of thought into the animation using the actor's own body.  they will even have the actor act out some moves on a special stage to make face movements, etc perfect.
