If Tom Cruise as kung-fu master in Mission: Impossible 2 wasn't hard enough to believe, what about those snazzy gadgets?  EW asked experts from high-tech design firm IDEO and MIT's Media Lab to accept this mission:  Evalutate the plausibility of the film's doodads.

Voice simulation strips worn on Cruise's throat
Difficult or Impossible?
Theoretically possible.  IDEO's Rickson Sun notes that similar technology -- electric charges that stimulat muscles -- is now used on quadripeligic's limbs.  So when can we find one for Fran Srescher?
Years to reality: 10

Sunglasses doubling as video screens, displaying the mission
Impossible, ays MIT.  While clumsy headsets with LCD screens currently exist, lense of normal shades are too close to the eye to project clearly.
Years to reality: Infinite

Camera that means tracetrack images to Ving Rhames' van
Though digital cameras at your local Circuit City can't transmit data wirelessly, MIT's Wesley Chan says there will so be prototypes that can.  Maybe Blair Witch III can skip theaters entirely.
Years to reality: Less than one

The tiny global positioning system chip in Thandie Newton's ankle (used to track her)
With current technology, that chip would have to be about the size of a refrigerator.   The problem?  You'd need a massive battery to beam Newton's position to a satellite, says MIT's Wendy Ju.
Years to reality: 25, at least
