Mission: Impossible Special Collectors Edition Easter Egg - Hidden Trailers for Mission Impossible 3

You must have the "Mission Impossible Special Collector's Edition" (not the standard version).

Go to Special Features, and highlight the "IMF" logo in the lower left hand corner of the screen. It will be highlighted in red. Click on that and you will find an additional trailer for "MI: III".

You can also do the same thing when you go to the 2nd page ("More") of Special Features - highlight the "IMF" logo on the lower left hand corner of the screen and it will give you another version of the MI: III trailer.
