Bourne Identity, The - Which Hand Is the Watch On?
In the makeout scene between Matt Damon and Franka Potente, it starts out with Damon touching Potente's face with his left hand, with a watch on his left wrist. But then it cuts to another camera angle, and he's suddenly touching her face with his right hand, and the watch is on his right wrist.
I thought this myself at first but for maybe a second or two at the end of that makeout session the camera zooms out a little to show it is filming the reflection in a mirror and not the pair of them directly. Why would they do this? Maybe just to get you all confused.
