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

Some good suggestions above, and Mark hit it with his comment that we need to know a bit more of the flavor of the work to comment in detail.

That said, here's my $0.02:

Set a low, even base light from overhead - maybe slightly blue? - and keep it low enough to just barely be able to see the actor(s). And enough to keep the pic from going too noisy if yo're shooting HD instead of film. Add just a bit of fog - not enough to add "fogginess" (that takes a lot) but instead just enough to diffuse/scatter the light some.

If there is a door (or two) then blast a powerful light under the door to add some atmosphere and make it look as though life is going on offscreen. The fog will also pick this up and accentuate it.

If you're dollying backwards down the hall, consider a couple low-wattage instruments off to each side, and move them along with the dolly, so they're in constant spatial relationship with the camera yet not directly in front of the talent.

If there's any space for a "practical" or two in any way, use them.

Some or all of these may be useful, or none of them. Again, knowing more about the script nad setting would be very useful.
