Walk into any kindergarten classroom in the English-speaking world, and you will find a Dr. Seuss book. I will bet money on it. Theodore “Seuss” Geisel has cast his spell over the world’s children for decades now; his whimsical wordplay, curious characters and surreal settings win over hearts young and old. “But David,” you wonder, “What on earth does this guy have to do with animation?” Well, this year we celebrate the 50th anniversary of the classic Dr. Seuss’ How the Grinch Stole Christmas!, the perennial holiday favorite that gave us the oft-applied “You’re a Mean One.” The 1966 Grinch is certainly the best-remembered adaptation of Seuss’ work, but it’s not the only one. Let’s delve into the long history of Seuss’ relationship with animation, and see where it’s going in the future.
