Steven Speilberg directing Jurassic Park

Below is some interesting video from the Electronic Press Kit sent to television stations to promote Jurassic Park.  The clip comes from Mike Carroll, who promotes a one-man-band approach to filmmaking in his book Naked Filmmaking.  (The book is great.) He wrote on his blog:

This clip shows Steven Spielberg on the set of Jurassic Park directing actors, blocking the scene, and operating his own Panavision camera and skillfully working the geared head wheels, one of the hardest feats to master. Notice how quickly and efficiently he works. Early in his career he was known for doing ten to twenty takes on everything. Here you see him grabbing shots in one or two takes. Speed, efficiency, and doing things yourself saves time & money.
