A deep, deep dive into the history of Disney's animatronics

The Defunctland YouTube channel has just released a video documentary on the history of Disney animatronics, and as usual for creator Kevin Perjurer, it is a deeper dive into the subject than you'd ever suspect. It starts in Ancient Egypt, lingers in the 18th and 19th century Europe for quite a while, and exhaustively covers Walt Disney's early interest and successes in creating mechanical creatures and humans before concluding at one hour forty-five minutes and revealing (Spoiler Alert) that it's only Part One.
