The reason he showed "no emotion" was because they had already met.

The way it should have been done was to have the camera running (guerilla style) and just shoot and deal with what you have. At least the response would have been more genuine.

I work in the film industry doing sound work. They had to set lighting and place lavaliers (mics) on the two men. So that shot took about 1 hour to do with all the takes etc... This is what made the SJ Parker so hard for me to like. She overdid her acting (reactions) to information presented to her. My two cents
