Ice Age 4

Animated family movie Ice Age 4 Continental Drift has cracked the U.S. box office chart and knocked Spider-man from number one.

The fourth installment of the prehistoric franchise, featuring the voices of Ray Romano, Denis Leary and Jennifer Lopez, grossed $46 million to open in pole position, ahead of Andrew Garfield's web-slinging performance in The Amazing Spider-Man.

The superhero film, another of Leary's projects, falls to second place with $35 million in its second week on release, while Mark Wahlberg comedy Ted takes third with additional earnings of $22.1 million .
