YEP, the Ice Agers are still surviving. The crazy crew of hilarity-enducing animals returns this summer for a fourth installment to the Ice Age franchise. In Ice Age 4: Continental Drift, the glacial creatures are somehow skipping thousands of years of evolution and geological history to stumble through continental drift in the latest piece of the series. With the original voice talents of Ray Romano, Denis Leary, and John Leguizamo, Continental Drift looks to be yet another quality kids' flick that will be enjoyed by kids and their parents alike this summer. For the numbers, the previous Ice Age movies made $46M (Ice Age), $68M (Ice Age: The Meltdown), and $41M (Ice Age: Dawn of the Dinosaurs) in their respective opening weekends. The question is whether the franchise can keep trucking (and compete with Madagascar 3 and Brave for the biggest animated films of the summer), or if it's lost some of its original steam by this point.
