Eddy Goldfarb has spent a lifetime making toys and is the creative genius behind many of the most popular toys and games of the 20th century. We may know them from movies or from our beloved childhood memories. But few know the man behind each design, an inventor with more than 800 patents. This inspiring documentary takes us inside the mind and workshop of the man who invented the classic marble-and-sticks game Ker-Plunk!, the toy-turned-collectors’-item Stompers cars, and an iconic gag that permeates American pop culture to this day: the wind-up chattering teeth. At 98 years old, a still-sharp Eddy Goldfarb uses curiosity, creativity, and optimism to keep inventing and remain young at heart. Tenderly filmed by his daughter, this loving portrait of Eddy's colorful life is bursting at the seams with bobbleheads, prototypes, and fanciful objects that inspire his creations.
