depends on the location , camera angles , boom as you know have to be out
the frame
in some cases it become as the secondary sound to mix with the radio mics
only abit open the sound
in most cases the actors backed up with lavalieres so you have close
micking as well
in good soundproof studio or extremely low nose locations 6 feet is
something that you can work without any problem as long the actor doesn't
mumbles or look down

In the bonus sections they showed some behind-the-scenes
and I noticed that the boomed mic was 6-8 feet off
the characters when they were engaging in dialog.
Isn't it hard to get crisp dialog with the mic that far
off?
