Expectations for the third installment of Po's adventures are high. And recent predictions of global grosses trend toward the rosy.
Kung Fu Panda 3 Box Office Predictions
Opening Domestic Weekend: 75 million
Total Domestic Gross: $235 million
Worldwide Grosses: $710 million
From where IMDB draws its information, I have no idea. But the figures above are in line with the first two installments, which made $631,744,560 (#1) and $665,692,281 (#2). So $710 million in worldwide grosses? That would be right in line with the box office growth of the first two.
