Just another note to add to this interesting discussion.
It's not just boom mikes. If you watch the videotape of NORTH BY
NORTHWEST on a video projector, or if the masking on a 16mm. flat print
isn't quite right, you'll see the tops of the cutaway taxicabs in New
York and the cycloramas used for background in several scenes (eg., the
reunion scene near Mt. Rushmore). Then compare the letterboxed
laserdisc version. It's a useful classroom example!
