Question: How does Mrs. Smith get to know that her husband is the shooter?
Answer: It comes down to a deleted scene. And I remember it as clear as day from when I saw it at the cinemas. There is a scene where Jane is brushing her teeth at the basin. John walks into the large bathroom and begins to take a leak. As John finishes up, Jane looks over her shoulder at him, just in time to see him lift one leg and give it a couple of sharp shakes. Later in the movie, after the ailed assignment/shootout in the desert, Jane is watching the footage of the other assassin doing the very same memorable action. Right as she is in the middle of replaying it back a couple of times, John turns up at her building, and one of her agents who has answered the intercom says, "Jane, it's your husband." And that is when the penny drops! For some bizarre, unknown reason, they removed that very important key bathroom scene from every TV and DVD release, leaving people who did not see the theatrical release at the box office asking the question of how Jane realized it was her husband.
Answer: From the way he stands and moves, height, weight and general mannerisms.
Answer: They worked for different agencies and were unaware that they had been given the same target (Diaz?) to kill in the desert. Mrs Smith initially thought that Mr Smith was a civilian that just happened to interfere with her assignment. She was given 48 hours to identify and eliminate (kill) the "witness." While reviewing the videotape of the scene, all Mrs Smith could see was the back side of the "civilian." While still looking at him, a secretary or similar employee yelled from outside the room that Mrs Smith's husband was on the phone and was back from his trip to Atlanta. By the secretary saying, "It's your husband" during the time Mrs Smith was looking at his back side on the tape, plus the information that he was back from Atlanta, it became obvious to her... and she wondered how she could have been so stupid to not know before this time.
Question: After John and Jane killed all those people, wouldn't their boss send more people after them? And why don't the Smiths fear/anticipate/react to this fact/possibility? Is it me or does it seem the only way they could have a happy ending is die or they have to kill the boss and destroy all their records (Which they would probably die trying).
Question: I understand that John and Jane work for different agencies but who does "Tank" work for? It seems unlikely that two competing agencies would need to bring in a third to solve the Smith problem, as they could both easily arrange for their deaths within their own organisations.
Answer: 'Tank' works for Jane's agency. At the beging he is being watched by David Keith who is Jane's boss (Seen briefly with a pixellated image on her computer screen).
Question: Sort of a technical question, but what type of camera was used to make this movie, film or digital? Also, there seemed to be a lot of shots made with a hand-held camera, was there any reason for this other than the "cool" factor of the camera moving through the shot? (The hand-held shots are generally the shots that are more "shaky" and such).
Answer: The director, Doug Liman, likes to do hand-held shots.
Answer: She notices that he shakes his right leg twice after peeing, just like her husband.
