In the distant future, the year 2000, my high school history teacher wheeled in the miraculous bulk of the media cart. Movie day. But even better, because technically prehistory is part of history, we were going to watch Walking With Dinosaurs.

It’s hard to overstate how big a deal the show was at the time. When the first episode aired in England, 15 million people watched. The show was incredibly expensive to produce, yes, but the results were award-winningly undeniable. The epic dinosaur show gave us everything from spinoffs, sequels, and imitators but also, of course, the magical Liopleurodon.
