Hey. I saw Mr. Popper's Penguins as an advance screening last Saturday and you're right. I could tell once Captain (the first penguin Tom Popper Jr. receives from his late father) was shown, he was CG. I know that real penguins were in the film, but most of them were all made thanks to computers. Also, I wrote a review of it and Judy Moody and the NOT Bummer Summer on my blog if interested.
