Re: Lighting a hallway for a night shoot. With no natural light source (IE no windows for moonlight)

I've done this shot dozens of times on soap operas and the best solution to is use the one Rick Wise mentioned -- have all the actors carry flashlights, and let them light each other's faces. (use a Roscolux matte silk diffusion #113 in the lens to help spread the beam) It's believable, and natural ...and answers the obvious scripting question as to why they're running around in total dark to begin with without some sort of "security" light ....especially when they stop and talk (which makes no sense unless the boogey man is chasing them -- in which case why worry about a realistic natural quality of light).
It's also wise to add as much backlight as possible as that will "edge" your actors and provide shape to their movement and the space they're in -- without making it seem like there's any light in the space. I've done the gimmick using 100w fresnels randomly buried up in the corners as backlight down the length of the corridor (obviously out of your shot). You could even use the smaller, cheaper, 50w or 75w "birdies". Gel them light blue (perhaps Rosco #63).
I also recommend a few 375w, 50 degree Source 4 Juniors equipped with break-up gobos and blue color (Rosco #68 works well). Be sure to use dimmers to also keep the intensity down. Dedo's are always my first choice, but it sounds like you don't have the money. Longer lens units will assist you in lighting the far ends of the corridor while still being able to hide the fixture. Let the actors run through the colored textural break-up and they can actually "settle-in" to a pool of texture when they do their dialogue. Some of my favorite non-descript break-ups for this type of gimmick are the GAM or Rosco "Construction", "Glass brick-up", "Squares", or even any one of the "linears".

have fun wih it.
