Few individuals have had an impact on the childhoods of millions and the imaginations of people of all ages like Jim Henson. From Sesame Street to The Muppet Show to The Dark Crystal and Labyrinth, Gen Xers grew up with Henson's magic being a familiar and comforting presence. And to this day, over three decades after his death, the characters he created are still household names.For those of us who were raised on Big Bird, Bert and Ernie, Kermit, and Miss Piggy, Henson's creatures feel as real as any living, breathing performer from our childhoods. But it's not just because we were kids when we were introduced to them. Even adults who met the Muppets found themselves transported into Henson's imaginary world, and after seeing interviews of the puppeteer with his creatures, it's easy to see why. Watch: Henson didn't even pretend to not be controlling Kermit. He didn't bother with ventriloquism. And yet, Kermit feels truly alive and separate from the person animating him. It almost feels surreal. Or perhaps just...real. Henson's characters even convinced film crew membersBoth guests and crew members alike found themselves pulled into Henson's world, even while fully understanding that the puppets were being controlled by people. The crew would sometimes move the boom mic to a puppet instead of the puppeteer. Directors would sometimes give stage directions directly to the Muppet instead of the human animating it. Dick Cavett, who interviewed Henson with his Muppets, said, “No matter how much you know about this, it’s completely convincing.”Even when a Muppet would explain the fact that the person was speaking to a puppet, it still seemed like a sentient being. Case in point:(This may be the one time you see Henson swear, but in context, it's brilliantly wholesome.) @guygilchrist My old boss’s last public performance as Rowlf.
