Trivia: Peter Graves was asked to reprise his role as Jim Phelps for this movie. When Peter found out that Jim was the main villain for the film, he promptly turned it down.
Trivia: Originally, Alan Silvestri was hired to write the score, but it was eventually decided that his musical style clashed with the tone of the film, and he was replaced by Danny Elfman.
Trivia: Director Brian De Palma reportedly had creative difficulties with Tom Cruise, who was also a producer and thus had final say in the decisions made during production. While this has been disputed, many have noted the fact that De Palma did very little press for the film (including "politely excusing" himself from scheduled media interviews at the last moment) and never took up an offer to record an audio commentary for the film as evidence.
Trivia: The last major Hollywood film to be released on the Betamax video-tape format.
Trivia: An early draft of the script was set to feature several characters from the original series all being killed off to raise the stakes for the new characters. The producers wanted to bring back as many of the original actors as possible. All declined, as they felt it was disrespectful to the original series. As a result, only the character of Jim Phelps was brought back, albeit as a surprise villain and not a hero.
Answer: Jim has not been paid (at least in full) yet. This is revealed in the conversation Ethan has with Max in the car. Payment was conditional on the disk passing all her safety checks, which she had not done yet (she had not even looked at it yet). There is no way Jim knew the NOC list was junk at this point in time. However, since Jim has not been paid yet for the NOC list, he might have been trying to play it safe, and have Claire just keep tabs. If things don't go as planned, he might have left Claire as she was expendable to him. Also it is unlikely Max contacted Jim (Job) to ask about the email from Ethan (pretending to be Job). Max at this point believes the two are the same person. She simply invites Job to come in and discuss further.
