Which of these animated films became a franchise?

The Ice Age franchise, produced by Blue Sky Studios (now owned by Disney), took audiences on a prehistoric adventure filled with humor, heart, and endearing characters. Kicking off with Ice Age in 2002, the film introduces Manny the wooly mammoth, Sid the sloth, and Diego the saber-toothed tiger as an unlikely trio navigating a world on the brink of a massive ice age. The franchise continued to evolve with several sequels, including Ice Age: The Meltdown (2006), Ice Age: Dawn of the Dinosaurs (2009), Ice Age: Continental Drift (2012), and Collision Course (2016), each adding new layers to the characters' journeys.
