I'm only about a quarter of the way through the book so far, but already I'm searching out videos of some of his earlier work. Here are some of his first commercials and also some of the first times he added his voice to his Muppets.
This clip from his Academy Award nominated short, Time Piece, features a young Jim Henson.
And here's Kermit being interviewed by Johnny Carson (originally Kermit wasn't a frog but more abstract and also blue-green rather than green, made from Jim Henson's mother's old coat).
I still miss Jim Henson. What a talented person!
I hope you enjoyed this. If you're interested in seeing more, there are many videos on the Jim Henson channel on YouTube. And I highly recommend the book.
Have a great day!
