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: Kittridge may still have suspected Ethan, but the point of the glasses and watch was to show him that Phelps was still alive, throwing the whole case open again. Ethan would have been cleared in the eventual investigation.
