How the Steadicam changed movies

Garrett Brown described the act of invention as "looking at something annoying and imagining it didn't have to be." What Brown solved was the shakiness of a handheld motion picture camera, allowing the camera frame to float like a butterfly alongside Sylvester Stallone up the steps of the Philadelphia Museum of Art in an iconic shot from "Rocky." Brown's creation would free filmmakers like Stanley Kubrick and Martin Scorsese from the restrictions of dolly tracks, and change the vocabulary of cinema. Michelle Miller talks with Brown, and with Steadicam operator Michael Craven about the revolutionary device.
