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

If the hallway has an el at one end, you could put some light there and shoot the scene heavily back-lit, seeing them more in outline than from the front, and letting them get darker as they move down the hall towards you with you dollying backwards. Ramp the spooky music and sound design at the same time, and it can really set a mood. If one of the characters smokes, lighting up in the hallway is a classic (if overused) "practical". You might work with extreme face closeups using the cherry end of the ciggie to motivate some momentary reddish-orange fill onto the face... just thinking out loud. So much depends on the art direction and needs of the script here, it would be ahrd to just name a perfect soulution without more data.
