In the episode where Chuck (Abby's assistent) framed Tony, there was two Tony's. Tony's look alike was in the jail cell with the real Tony during the point of him interigating himself like they would on a witness stand. The DVD commitary for this episode has Micheal (tony) telling Pauley (abby) he was talking to a look alike instead of nobody.
Where in the sequence do you mean? when each actor is introduced they have a closeup and an action shot both on screen at the same time. you'll have to be more specific
the opening credits showed the scene when tony is screwing around in the intrrigation (srry cant spell for my life) room, but two parts playing next to eachother to make the opening more interesting. i think it looks cool =]
There was an episode where Abby's assistant Chuck I think it was, framed Dinozzo for a severed leg some teens found. He was in the interigation room just messing around because he knew he didnt do anything.
