A friend of mine works in film, so I know the ballpark costs from conversations with him. You can find production costs for films on the net fairly easily.
Puss in Boots, for example was $130 million and Kung Fu Panda 2 was around $150 million. So you're looking at 1.25m to 1.5m per minute.
It can take a week just do 3 seconds of animation and all the labour is, of course, exceptionally talented and extremely expensive.
