In most James Bond, Tom Cruise movies, the bad guy has an innovative idea/product to destroy the world.
But in the MI3, the most interesting thing about this movie was that it had a mention of the word rabbit-foot. All Tom Cruise knew was that it should not land in wrong hands. But it always remained a mystery what this rabbit foot was, how it worked and how it can destroy the world.
Call it deviation from the norm, or a start of the new era, but people do seem to have liked this change.
