CG animators Michael Thurmeier (who worked on
Ice Age and its sequel, Ice Age: The Meltdown) and Chris Renaud (who worked on
Meltdown), pull a character from that franchise for their 7-minute animated short No Time for Nuts. That film finds Scrat, the acorn-obsessed squirrel from the first picture, digging through the ice to bury a nut - and happening upon a time machine instead. ~ Nathan Southern, All Movie Guide
