If you?re looking for proof why Tom Cruise has been an action movie mainstay since the 1986 blockbuster Top Gun, you don?t have to look very far. His commitment to acting craft ? particularly in his Mission: Impossible films ? is all up there on the big screen, as Cruise rarely uses stuntmen to suspend the disbelief of his audiences. The wonderful thing is, as Cruise, 54, moves on in his years, he seems to up the stunt ante with each M:I picture that comes down the pike.
