The trick is to have the action on a low hill or rise so that you have room to light from below. The advantage is that you can shoot low angles.
The trick to lighting the haze so there is an omnipresent light source (being the haze), is to use a very even diffuse source. Blondes strung over-head or on scaffold towers would probably be too sourcie (sp?) to work. How Shelly Johnson was able to separate the layers of trees and characters by lighting haze was, as David posted, to use large lights far down an embankment and diffuse them heavily so that they would spread evenly before reaching the action area.
The 6' Color Kinetics ColorBlaze 72 RGB LED
A low budget approach that would accomplish the same thing without a steep embankment or large HMIs would be to use a ground row of Color Kinetic ColorBlaze 72 LED fixtures. Each fixture is 6 feet long and can be strung end-to-end to cover a long distance. If you use the newer dmx four channel RGBA fixture, you will be able to dial in with a dimmer board the color blue you want without losing output to color gels as you would with your quartz blondes. And with a maximum draw of 420 Watts at full output you can operate up to 15 of them (enough to cover 120 linear feet) on a 7500W modified Honda EU6500is - which will save you having to run feeder cables through the woods (there is nothing worst than running cable through woods at night.) In fact, you could probably light your entire night scene with nothing more than a couple of 7500W Honda EU6500is portables just as the makers of “Gasp” did (pictures attached).
But, beware, their power factor deteriorates as they are dimmed or only single color emitters are used. Which means that they will draw current rich in harmonic distortion, which will have severe adverse effects on most portable generators. The harmonics generated by these lights, and any other non-Power Factor Corrected sources (HMIs, KINOs, LEDS) you might use, can cause severe voltage waveform distortion and higher than normal return current on the main neutral conductor which can result in it overheating and catching fire.

For this reason, I would not operate them on conventional AVR putt-putts through splitter boxes, but only through an inverter generator (like the Honda EU6500is) and a transformer/distro with super neutrals (use this link for details.)
