If you caught Mission: Impossible Ghost Protocol then you probably noticed that series regular Ving Rhames was reduced to a mere (uncredited) cameo as Luther Stickell. It seems that this might be remedied for the upcoming fifth movie.

Or it could be just another cameo. But speaking of Mission: Impossible, these seem to me to be the movies The Expendables series tried to head towards in tone. But one is beer the other is cake, each working for their own reasons. Well Mission: Impossible works at least.
