@Murphy: It's called lifts and camera angles. Works wonders.

Cruise was at least 1 inch taller than her

If you look carefully, you can see the tricks they use to make Cruise seem taller. Tom's always closer to the camera, and sometimes, he'll step closer to the camera (away from Kelly) in the middle of a shot, i.e. in the scene with the motorcycle and her car outside his house.
