Back when the Earth was being overrun by glaciers, and animals were scurrying to save themselves from the upcoming Ice Age, a stupid sloth named Sid, a woolly mammoth named Manny, a saber-toothed tiger named Diego, and an acorn-loving saber-toothed squirrel named Scrat are forced to become unlikely heroes. The four reluctantly come together when they have to return a human child to its father while braving the deadly elements of the impending Ice Age. —IMDb
Carlos Saldanha (born July 20, 1968) is a Brazilian director of animated films. He was the director of Ice Age: The Meltdown (2006), Ice Age: Dawn of the Dinosaurs (2009) and Rio (2011), and the co-director of Ice Age (2002) and Robots (2005). Saldanha was born in Rio de Janeiro, Brazil. He left his hometown in 1991 to follow his artistic instinct and passion for animation. With a background in computer science and a natural artistic sensibility, he found New York City the perfect locale to merge these skills and become an animator. He attended the MFA program at New York’s School of Visual Arts, where he graduated with honors in 1993, after completing two animated shorts, The Adventures of Korky, the Corkscrew (1992) and Time For Love (1993). The shorts have been screened at animation festivals around the world. At SVA, Saldanha met Chris Wedge, one of the cofounders of Blue Sky Studios, who invited him to join their growing team of artists. —Wikipedia
No matter how silly the franchise gets over time, and how fun Scrat is to watch, the Three Men and a Baby story of the first one will always be the most charming, not to mention the darkest.
