If you've created a two shot on the couch, in a flat space, camera 90º to the talent, isn't it reasonable to say that if you start moving the camera you'll lose the flatness by revealing perspective of objects?

If enough of the couch is shown, (camera static) wouldn't it reveal perspective and "spoil" the flatness?

Am I confused?

If I understood your question...

 

If the talent is sitting on the couch, the couch itself will remain in focus as long as the talent does.  What you can do is put some distance between the couch/talent and the background and choose what would be the proper focal length lens to achieve a perception of depth by dollying the camera in along the z-axis.

 

Secondary movement - specifically pans, tilts & zooms - may make your shot more dynamic, but they won't add a sense of depth.

Sure a camera move will usually create some depth cues but it is a matter of degree -- if someone is standing against a wall and you dolly in on them, especially with a medium to long focal length, there wouldn't be much depth cues to distinguish the shot from a zoom in.
