Here's a perspective you've probably never seen.

A camera was attached to the steadicam rig and rolled while the final sequence of Hugo was
filmed.

Hear the exhaustion of the operator at the end. Enjoy the perfectly timed wisecrack (quite possibly from the director). And watch in amazement as a professional boom guy ["it's tough to be the boom guy"] navigates through doorways and around the cameraman.

This is something you'll hardly ever get to see. And thank you to 'mirrorvids' for posting it.
