Ice Age: Dawn of the Dinosaurs

Ellie (Queen Latifah)and Manny (Ray Romano) are expecting their first child, and Manny is obsessed with making life perfect and safe for the family, since his first experiences as a husband and father went bad when his family was killed by hunters. At the same time, Diego(Denis Leary) finds himself unable to catch a cocky gazelle (Billi Hader) he has been stalking and decides to leave the herd, believing that he is losing his predatory nature as a tiger. Sid(John Leguizaamo)grows jealous of Manny and Ellie and “adopts” three apparently abandoned eggs that he finds in an icy underground cavern and call them Eggbert, Shelly, and Yoko. Manny tells him to put them back, but Sid instead looks after the eggs, which hatch into baby Tyrannosausus the next morning.

Although Sid tries his best to raise the three dinosaurs, their rambunctious behavior scares away all the other animals’ young and ruins a playground Manny built for Ellie’s baby. A female Tyrannosaurus, Momma, whose eggs Sid stole, soon returns and carries both Sid and her young underground, with Diego in pursuit.

Before they can exit the jungle, Rudy attacks at full force; Buck lures Rudy away from the group and is nearly eaten himself, before Diego saves him at the last second. They then ensnare him briefly, but he escapes and resumes his onslaught. The herd is saved by the timely arrival of Momma, who charges at Rudy and knocks him off a cliff before roaring her victory. As she and her children wish Sid well, Buck – now without a purpose in life since Rudy is gone – decides to join the herd and live on the surface. However, a distant roar tells him that Rudy is still alive; he changes his mind and sends the herd home, blocking off the path to the underground jungle at the same time so that no one else can go down there. Manny and Ellie welcome Peaches into their frozen world and admit that Sid did a good job looking after Momma's children (though Manny tells Diego that he will never let Sid babysit Peaches). Diego decides to remain with the herd, while Buck stays where he wants to be: underground, battling it out with Rudy.
