Fan Casting Ice Age (Remake Live Action)

Scrat, a saber-toothed squirrel, attempts to find a place to store his acorn for the winter. Eventually, as he tries to stomp it into the ground, he inadvertently causes a large crack to form in the ice that extends for miles before setting off a large avalanche which nearly crushes him. He barely escapes but finds himself getting stepped on by a herd of prehistoric animals migrating south in order to escape the forthcoming ice age. Sid, a clumsy ground sloth, is left behind by his family and decides to move on by himself, but is attacked by a pair of Brontotheres after accidentally ruining their meal and making them angry. Sid is soon rescued by Manny, a bitter woolly mammoth heading north, who fights the rhinos off and continues on his path. Sid joins Manny, not wanting to be alone and unprotected.
