Ice Age: Dawn of the Dinosaurs trailer is on MSN

A new trailer has gone live on MSN for Ice Age: Dawn of the Dinosaurs, the third film in the animated franchise.

In the 3-D animated movie, Scrat is still trying to grab the ever-elusive nut (while, maybe, finding true love); Manny (Ray Romano) and Ellie (Queen Latifah) await the birth of their mini-mammoth; Sid (John Leguizamo) the sloth gets into trouble when he creates his own makeshift family by hijacking some dinosaur eggs; and Diego (Denis Leary) the saber-toothed tiger wonders if he's growing too "soft" hanging with his pals.

On a mission to rescue the hapless Sid, the gang ventures into a mysterious underground world, where they have some close encounters with dinosaurs. Ice Age: Dawn of the Dinosaurs opens July 1.
