Yep... someone created a youtube channel called TrailerCats. Their first production? Take Tom Cruise's face in all of his scenes from the Mission Impossible 4 Ghost Protocol movie trailer - and replace them with the face of a cat. That talks. This took some work!
You may have been skeptical of another MISSION: IMPOSSIBLE film. You may have said it was not necessary, or that Tom Cruise was done, or that a director who's known for animation may not be the best choice for an entry of such a well known franchise.
