Check out the Tiffen DFX for Video plug-ins. Besides all the different looks, it also offers a "Gobo" feature that does exactly what you're looking for, adding the lighting effects to the background. An associate took a very plain video of a subject in a messy office, then added a color effect...
I've seen demo clips of how to do this using "Mocha" tracking software with After Effects. Very effective results creating monster eyes in the demo I saw.
