NEW YORK -- With Batman lurking, the prehistoric critters of "Ice Age: Continental Drift" ran off with the box office, earning $46 million in their opening weekend, according to studio estimates Sunday.
The animated film from 20th Century Fox is the fourth in the "Ice Age" series and the first in 3-D.
The North America performance of "Continental Drift" was on par with previous "Ice Age" movies but well below the opening weekend of the second installment, "The Meltdown," which opened with $68 million in 2006.
While it was this weekend's winner, "Ice Age" won't have much time to savor the victory. That's because it's likely to be a one-and-done winner -- as the latest edition of "Batman" hits the screen this coming weekend.
But for now, "Ice Age" is the box office leader.
The animated film features the voices of Queen Latifah, Ray Romano and John Leguizamo.
Number two is "The Amazing Spider-Man" with $35 million, followed by "Ted" with $22.1 million, "Brave" and "Magic Mike."
