Moving a subject from left to right if shot in front of green screen

Here's my question:

If I shoot an interview with someone who sits right in front of a green screen in the middle, is there any way I can move that person, and that person only, to the left or right of the frame after it's shot? I have seen it in VH1 and it looks great. Do I have to roroscope? Would I have to shoot the interview 3 times in front of the green screen, One on the left side, One on the right side, and one in the middle?

Any help would be appreciated

Thanks in advance

Well, assuming that you are keying out the entire background, you're left with the subject pretty much just floating in space. So its pretty simple to just move your subject layer to either side of the frame, independent of whatever background layer you plan to put behind him/her.

Of course, as you move this person, their eyeline may appear as if they're looking at different subjects.

If you have no keyed out the entire background, I'm afraid you are left to play with masks.
