I came across this video today and had to share it. At four-minutes long, it has to be one of the longest steadicam-action sequences ever recorded with no edits. Apparently it took over a month to get just right, and the film lost one cameraman because he became too frustrated with the sequence.
It's not new--according to IMDB, "The Protector" came out in 2005--but it sure is entertaining to watch. Take a look.
