Hmm, well basically here at the agency I am working at we are trying to do some more video work. My questions is - is it possible to take footage of an individual, then erase their entire head, and replace it with another head (a 2D head)? Hope to hear from someone soon. Thanks a ton.

If the person was shot greenscreen, it could be a simple matter of masking off their head and replacing it on a new layer.
If you're talking live-action footage shot against a normal background, there are two options I can think of:
1. Place the 2D head over the actor's head, maybe even using motion tracking to stick it in place. As long as the 2D head covers the actor's head entirely, the effect will work ok
2. Remove the actors head using cloning tools so that clean background plate is left where the head used to be. Then use the above method to attach the 2D head to the body.

I am looking to do the same thing, shooting a moving shot and then replace the head with a 2d or 3d image. Do you have any links or references to tutorials or books?

you could look at the tutorial from andrew kramer, (www.videocopilot.net) where the actors head is blown of.
If you have a shot of the background without a person, then the same shot made but then with 1 person who's head has to change (note:do not change the camera angle or anything else). then you can simply mask(masking tools like pen tool etc) his head away (you see just his body with the background, because you shot also the background without a person, that layer is under it) and replace it with a head that's from another layer.you see?
