For the past 45 years Caroll Spinney has been Sesame Street’s Big Bird and Oscar the Grouch, and, at 80 years old, he has no intention of stopping. By way of a Forest Gump-like journey through American history, Spinney’s personal stories are a look behind the scenes of one of the most iconic and well-known American television shows. With the aid of archive footage and photographs, I Am Big Bird tenderly draws a portrait of the man behind the feathers—an unsung hero to millions of children across the world and across the decades.
