I took my kids to see this at the drive-in 2 weeks ago. Very good movie. I think it was longer than 40 minutes though...
Edit: One fact I remembered was that the male penguin watches the chick, and goes without food for 3+ months. While the female walk the 70 miles to the edge of the ice to find food. Then she comes back to feed the chick, then he has to make that 70 mile walk to eat. This explains why there are more female peguins than males.....
